CentOS 5 :: System Lockups And Freezing?
Dec 20, 2010
I have a fresh install of CentOS 5.5 on small thin client system with a 80G HDDs, 1 GB ram [URL], I have run into an issue where the system just locks up and freezes and I can no longer access it, cant ping it, cant use webmin and cant view its web pages. The system seemed to be running fine unitl I left it to do some updates via webmin as it informed me there were 118 updates. I really only use the system as a LAN captive network server, and it is currently in the testing phase for this setup. The install went on with no issues and it ran fine, but now every so often within 12 hours it just locks up and I have to reboot. kdump shows no logs so I am finding hard to work out what is going on. but have installed it on 5 of my servers 4x ibm x335 and this . I intend to use the mini server for a captive portal system displaying advertising and promotions to wireless clients.

I"m a newish Ubuntu user, but have been running some flavour or other for the last 5-6-7 years. Anyway, I just recently installed Maverick and have to say it's polished compared to the last version I tried ( maybe 6? ).
I am however having a frustrating issue while surfing the web. After a 2-3 minutes using firefox, 5-10 minutes using chromium - the whole system seems to lock up solid. The mouse/ keyboard no longer respond. I've read through a few log files and nothing seems to stand out, though I may be looking at the wrong place. I plan on running some system monitors, and top when I get home to see if they show me anything. Just thought I'd come here to ask for any other things to have a look at.

it only seems to happen when im using wicd to change wireless access points several times in a short time span. i havent done anything out of the ordinary, installed packages off of sbopkg, and built my own kernel, but this happens in the stock kernel toothe following is what appears in syslog each time it happens
Code:
Mar 7 13:12:14 null kernel: [ 1.714177] WARNING: at arch/x86/kernel/hpet.c:404 hpet_next_event+0x5f/0x81()
Mar 7 13:12:14 null kernel: [ 1.714969] Hardware name: 3241

I'm having a bit of a problem with a CentOS install I'm working on.This computer is an Asus M2A-VM mobo with the latest bios and a fully patched CentOS 5.3 system.The system randomly freezes and I've been able to narrow it down to what i think is ACPI issues with the chipset since the system is rock stable if I use the ACPI=off option in grub. However, when I do, I get messages about OHCI and EGCI controllers not having the correct PCI IRQ or somesuch and my USB don't work. Since this system has a usb keyboard, mice and printer, that's a bit of an issue!The system boots fine but will freeze after a random amount of time, sometimes even during startup (after the X Window system has been opened).
I'm at the end of my rope here as I'm admittedly pretty new to Linux (about 2 months experience although I've succesfully set up 5 systems and a zimbra server in that time - slowly learning when I'm trying to do something) and I've been scouring the net to try and find a solution to no avail.I know this particular chipset seems to be very trouble prone if I look around but the only thing I could find about issues like mine was related to ACPI with the chipset but that supposedly solved in earlier kernel revisions (and I have the latest kernel).troubleshoot the defective part of ACPI on my chipset would be appreciated so I can turn off the offending ACPI "feature".
PS : I also get an error message when booting : ACPI expecting a [REFERENCE] package element, found type F7B953PC

Since upgrading to lucid, I have been experiencing regular system lockups. About once a day, my X desktop will disappear and I'll see a TTY with a few old console messages and at that point everything is completely frozen and I must hard reboot.
I have checked out various logs in /var/log and found nothing at all that indicates the system knew anything bad was happening. What is the correct approach to try to narrow this down?

My Ubuntu Karmic running system experiences random lockups. There is no pattern in when it will happen, it can go for days without one, or happen every couple hours. Only thing I can notice is that it happens most often when I run Firefox, but when it happens, it happens regardless of me having Firefox open on a website with lots of Flash content or not. When the lockup happens, I cannot move the mouse - the led light on my mouse shuts off, I can't move the cursor, the whole UI becomes unrensponsive, there is no blinking lights on the keyboard, REISUB does not work, only hitting the reset button on my case helps. After reboot, there are no indications of errors in any of the logs that I can see.I have ran memtest for 24 hours, and it completed without errors.
Additional information:
1. LSPCI output:
Code:
00:00.0 Host bridge: ALi Corporation M1697 HTT Host Bridge
00:01.0 PCI bridge: ALi Corporation PCI Express Root Port
00:02.0 PCI bridge: ALi Corporation PCI Express Root Port

I have CentOS 5.4, and am trying to install mailman.sudo yum install mailmanlook fine, tries to install Package 3:mailman-2.1.9-4.el5.i386, gets to "Installing: mailman [#### ] 1/1"and then freezes with #'s about 80% across. There it stays, until I kill -9 from a different shell.yum-complete-transaction just repeats the same experience.yum update works fine, everything else updates without trouble.

I have a clean install of Kubuntu 9.10 running on ext4 partitions (root and home). Kernel: 2.6.31-20-generic-pae.Freezing is becoming a way of life! I first thought it was my main browser (Seamonkey) but freezes have occurred even when it's not open. It usually occurs when computer is left unattended for a while.I'm not sure if it's the desktop crashing, no ides how to check logs especially as I have to reboot to gain access.
Mouse and keyboard work fine, I can use ALT+F4 to close windows and ALT+F2 to restart. But programs freeze, KMenu won't open, Taskbar is frozen, no HD activity.Where do I go from here?9.10 seems OK on my laptop but that was a upgrade from 9.04 and I don't usually leave it open unattended for any periods of time. I did a clean install of 9.10 after an upgrade was having the same problems.

I installed KDE 4.7 (minimal desktop install) on my desktop computer, running Ubuntu 11.04, and every time I go to log in with the KDE Plasm Workspace, my computer all of a sudden freezes up after about a minute of working fine. My mouse slows down incredibly and eventually comes unresponsive to keyboard, power button, and mouse click input. The mouse can move, but it's movement isn't fluid, and it can only move a little bit. Can anyone help me? I have also had problems with KDE 4.7 on other computers as well, but this desktop I am using is almost brand new. :/

I just did a fresh install of Fedora 15 last weekend. Since then I haven't had any problems with it except of course a few bug reports every now and then.Today, out of the blue, my system start freezing, giving me no choice but to hard reboot.As a particularity when the system freezes I can still move the cursor on the screen but everything else seizes to respond.It happens every time within 10 minutes after reboot, and even sooner if I launch the internet browser (behaves the same with both Firefox and Epiphany) or if I open a video file.

GNOME system monitor is constantly freezing and not responding when i click on first tab 'System' Do somebody knows some workarounds for this issue? It's the same on freshly installed system and also on updated GNOME 2.28 from stable repository.Sometimes on second or third atempt it is working, but i cannot accept such an level of unstability and bugs, discovered on daily basis of testing openSUSE 11.2. There are much more very basic issues in this release which are normal for beta stage, but not for almost 3 moths old system...

i recently switched from slackware to debian because my laptop kept freezing up on slackware, and now it's doing the same on debian on slackware i would get this error in syslog: "hpet: compare register readback failed" at the exact time of lockup, which would leave me with a blinking capslock led indicator, and a completely frozen system (not even magic sysreq sequence would do anything) now on debian, same symptoms only there's nothing in syslog, and no blinking capslock led hardware is: i7 720q intel pm55 chipset nvidia gt 240m laptop model is lenovo ideapad y550p this will occur both in X and at the console i am using my own kernel as the default kernel doesn't support my ethernet adapter i have tried disabling hpet at boot, but there was no difference i have tried the patch posted here

xine freezes completely and totem freezes when I resize video. Sounds like a library problem.

I've just installed F15 KDE Edition, and as the title tells, I need to keep pressing F2 and/or Enter to make the system go through the boot up process, otherwise it freezes as long as i keep it without my interference !! and then it takes relatively long time to start the GUI, and when I switch to the console (using ALT + CTRL + F3 for example) and try to write the login or the password, there seem to be some 'bouncing' effect, that if I'm to write the login 'root', I get something like 'rrooott' ... however, this doesn't happen in the GUI .....
I have a multiboot system, with Windows7 and Linux Mint (based on ubuntu 10.4) installed along side. While Windows7 doesn't have any problem with my hardware, Linux mint has also some issues that cause the performance of media players to degrade (sound and video tearing) and cause repeated freezes to some applications (a game actually, 'wesnoth') until I press a key or move the mouse.
I have AMD Athlon 7750 dual core 2.7 GHz system, with 3GB DDR2 800 Ram, and embedded ATI Radeon HD 3200 with about 512 shared memory.
one more thing, when I booted off the live image to run the install program, I booted into the video failsafe mode (not sure of the exact name, but I think you got it, no mode setting) and passed the option 'noapic', so I suppose this options are still passed whenever I boot mysystem, as I get the text version of the progress bar during startup, rather then the graphical fedora logo ( i.e no mode setting) ..

I'm using Ubuntu 11.04, Natty Narwhal, 64-bit. I've been using it since Alpha, and Firefox and xChat have always frozen my system. I update daily, so I know I'm on the newest updates, yet they still freeze my system. I've tried doing a total uninstall on both of them and reinstalled to the same freezes.

I have been working with Linux for some time now and moved from "crash-dummy fedora" to LinuxMint and now I'm on Debian 8.I ... The system is freezing and the only way to get it out of freeze is to kill tty7, I log into tty2 as root(which can startx) and kill tty7 via pid...
At first I thought it might be that I have 10 virtual NICs on 1 physical NIC, but after removing them it still freezes after a few minutes of running. Now I am wondering if double mounting/bind causes issues,
Example: drive2 is mounted to profile2/MyStuff, but I also "mount -o bind" a folder inside profile2/ MyStuff/.opera to profile2/.opera..
This is what I mean by double mounting. Does double mounting cause freezing ?Because I have not double mounted, and it hasn't froze yet. and to be honest, I am double mounting/binding several config folders like .mozilla etc...Drives are SSDs, and I created a complete other drive with LinuxMint and it froze the same way after mounts.

After migrating from openSUSE-11.1 to openSUSE-11.2 together with a few further online updates including a kernel upgrade to 2.6.31.8-0.1-desktop, my system started freezing a couple of times for two days.
I made up my mind googling for "linux freeze", found a hint saying, that 2.6.31.8 causes trouble, fell back to 2.6.31.5-0.1-desktop, and voila: the problem is gone. What a relief!
The following describes my system:

This is happening pretty often. when in ubuntu, usually while i'm browsing the web, my browser will go dim then a box will come up saying something along the lines of missing resources. the thing is, all my desktop icons will then turn to red x's and no text characters on any further boxes will show. when i restart it says grub error and takes one more restart to finally come on. i got fed up with it and switched over to windows 7 where my browser also froze and my computer froze up.

I have a bit of mystery regarding my system intermittently freezing. First off, the info. I using/running: Ubuntu 10.10, 64bit version (clean installation) Intel(R) Core(TM)2 Duo CPU E8500 @ 3.16GHz (not overclocked) 6GB RAM Nvidia GTX260 Nvidia proprietary drivers 1TB Western Digital HD (32MB cache) Now, the problem: A while ago, I started experiencing intermittent system freezes that would last for 2 or 3 minutes and happen about once every 45 to 75 minutes.
The Gnome System Monitor (GSM) would show 100% CPU utilization, but top, htop, and conky only show about 11% usage. I pulled up the process list in GSM. However, I had issues, for the obvious reason, when bringing it up when the CPU was spiking. Even when I could, it only showed the usual suspects (Firefox, Deluge, Ktorrent, and Xorg) running the high single digits. This was backed up in top, htop, and conky. I also checked the RAM, but usage was down around 25%, with nothing in the swap.
I checked the messages log, but there was nothing there. Nor in dmesg. At least not that my limited Linux admin skills could find. The freeze just happened, so I've attached them in their entirety. I've come to suspect that Python is the cause. It happens most often when I have Ktorrent or Deluge going. I used to use Deluge, but moved to Ktorrent to test if Deluge itself was the problem. They're both written in python though, and both seem to cause the slowdown. It also happens when other python-based programs are running, such as the updater, but not as much or as bad. Things I've tried to fix the problem:
- Clean install (first time in over 18 months)
- Updated Nvidia driver by adding a repository
- Updated Deluge by adding a repository
- Enabled backports.
- Gave my PC the finger
This is driving me nuts. If it was just BT clients, I'd only run those at nights, but it's also parts of Ubuntu itself that relies on python, which I really think is the problem.

since installing 11.04 on a computer that was running 10.04 perfectly, the system hangs for a split second every 10 seconds or so. If you make little circles with the mouse pointer you will see it jump position when the computer hangs briefly. If you are listening to audio or watching video then this also hangs for the same very short length of time.
I had the exact same problem when I tired going to 10.10 and so had to go back to 10.04. I was hoping it may just be an issue with that version but it seems not. The computer is: 1.6GHz Intel Core Solo, 1GB Memory, the motherboard is a Jetway Mini ITX board with integrated Intel graphics. It has no problem running the 3D stuff in Unity (or any of the old gnome desktops). Changing to 2D or turning off desktop effects in 10.10 does nothing to solve the problem. 10.04 seems to be the last time Ubuntu worked properly with the computer.

Flash is causing severe problems on my slackware laptop. It happens pretty much only when I go on ..... and playback starts. Then the whole screen flickers and everything freeze. I have no mouse or keyboard (cursor is frozen) and I need to SSH to the machine to kill the process "plugin-containe" whatever it might be.
SO basically, is there anything to do to prevent such problems?

Ok, this just started happening with ubuntu 9.10.
When it first happened, I didnt know what to do so i accessed all my data, backed it up in a diff partition, reformated my drives and reinstalled a clean 9.10. But now, every now and then (i think its when i use frostwire and have other programs running) my ubuntu keeps freezing up, it becomes non-responsive to anything i do, so i have to do a hard shutdown, after which, when i reboot, it is not able to mount /home, so i run FSCK and it fixes it, but ive done this about 3 times now, its starting to get a bit annoying, i dont know if anyone else has this problem, or if its a known bug. Here are my specs:
Running: Ubuntu Karmic 9.10 64 bit
3 Sata HDD: 1 TB, 750 GB, 350 GB
4GB Ram
2 Nvidia 7900GS
with a Pentium core 2 duo @ 3.0GHz

I've got a fun one for you. What makes absolutely any attempt to view a flash video crash Ubuntu 10.10, both in firefox and chromium? Lately, firefox began doing this. I switch to chromium, same thing. Also, the system completely locks up after about 30 minutes online if I can get the thing to work at all. When this happens, the rounded edges of all windows disappear, the menus become unresponsive, and any attempt to open the system monitor to end the offending process results in an "Unable to fork new process, system resource unvailable" something like that.
My entire online routine goes like this: open terminal, su to admin account to enable ufw (which will not run at boot no matter what I try), su to normal, limited account, open web browser, things explode (or work for 15 minutes before freezing completely.)

I have a fresh install of Maverick on a Toshiba r700 laptop PT310A-05N011. I am experiencing constant freezing. The computer will without warning completely freeze. Can not move the mouse or even drop to a tty shell. After about 5 seconds the fan will spin up to full speed. I then have to do a hard shutdown. Every time this has happened i have been connected up to a wireless network with firefox open while actively surfing the net. This issue did not happen before I installed the wireless driver (Broadcomm proprietary, downloaded through ubuntu Additional Drivers).
I'm not sure how relevant that is though as 90% of what i do on this laptop is surfing and i installed the driver a few hours after install. This freezing does not happen in windows 7 and I have left it running prime95 overnight once in both 7 and ubuntu without error. Does anyone know what this may be, how i might resolve it or steps I can take to diagnose it, logs i can check?

I've been having problems for a while with my pc at work and after a bout with a similar desktop I figured out that it somehow relates to the kernel updates from 5.3 to 5.4. I have two machines with identical motherboards (Asus M3a32-mvp), cpu ( athlon 64 X2 6400) and memory (8 gigs Corsair) with different video cards.
My desktop at work started with Centos 5.2 and was kept updated to 5.4 along the way. The other PC is my desktop at home and it started out at 5.3 and stayed there until recently mainly because my wife mostly uses it so I just never got around to doing updates.
Here is the problem, a while back the work PC started doing weird things, it would stutter, freeze up, sometime the mouse cursor would freeze into a cross hair and sometimes completely lock me out where even the keyboard wouldn't work so I had to kill power to reboot anf get control back. I eventually discovered that if I still had keyboard access I could jump to a console window, log in and killall nautilus or killall gnome-panel and I might get things back to normal for a while. I can even log in with another machine to use the killall commands if the keyboard locks up. I checked TOP during these episodes to see what was killing the system, I figured something was running a muck and gobbling up processing time or memory but nothing shows that appears to be off.
Like I said the home system was on 5.3 and not showing the stuttering problems so I even considered that the video card drivers might be causing something, that is until I tried to update the home system and got the same issues.
I had a hard drive failing at home so I figured I'd back up the data and reinstall the main system on a new one so I could start over with a clean system. This time I started from 5.4. Almost imediately I discovered the freezing problems after the complete install so after trying a few things I wiped and reloaded, couldn't mess around too long with it as the wife was really complaining about not having a PC, a 5.3 version. Bingo, now the system functions perfectly, no stuttering or freezing up. I then used yum updates to updates everything but the kernel. This also seemed to give me a system without freezes so I stopped there with the home machine.
Just to be clear the home pc used the standard yum repositories defaulted in the setup i didn't add any so it isn't a 3rd party repo causing the problems with the home machine. So it looks like the updates from 5.3 to 5.4 regarding the kernel seem to be causing me problems.
It's getting so bad at work I'm planning on wiping and reloading a 5.3 version and going from there but that's alot of work so I'd really like to just fix what is going on with the 5.4 version.

I installed FC11 from installation cds twice and I'm having a problem with Firefox freezing the system. The mouse cursor will move but nothing else is responsive, including mouse buttons and keyboard.I checked the media on every disc and they all check fine.I never had this problem with FC10. I tried upgrading Firefox -- with the necessary dependency upgrades too but without success.I tried to downgrade to FC10 Firefox and ran into a great big hassle with that.
