Software :: System Randomly Locks Up And Slows To A Crawl?
Jun 5, 2011
I noticed that sometimes my Linux server will randomly start to lag really badly, to the point where even a http request takes forever. It is an Intel Core2Quad with 8GB of ram running FC9. This is my "Everything" server so it does file, email, DNS, web (for local stuff only), VMs and so on. There are about 5-6 VMs running on it at any given time. I manage it through a VNC session and have some SSH consoles within that session. This way if I reboot my PC I don't lose all my SSH consoles. If I need to SSH to any server I do it from there. I treat it kinda like a terminal server to some extent.
When this slowdown happens, top is not really useful because I also do F@H so that will always be to the top, but it's low priority. The VMs are also always near the top. This does not change whether it's slow or not, so when it's slow, I have nothing to go by on how to troubleshoot. The load does seem to skyrocket though. Right now it's doing the slowdown thing and it's at 8.09. Normally it's at around 3 which imo is good as it it's under 4. I have 4 cores so anything more than 4 means it's queuing. At least that's how I understand it. This is the output of top:

I started unarchiving a RAR file that this several gigabytes big. The computer is now going really slow, it's almost frozen. Sometimes I can move the mouse a little, but that's it. The unarchiving process seems to have halted, so now all I can do is restart the system. I don't think I can unarchive this file in Linux.

I was just curious for the ATI users out there that are running KDE on Fedora 14 have any of you experienced any performance issues? My systems desktop slows to a crawl when Kwin's compositing is enabled, however in KDE 4.4 there were no issues at all. My desktop I built is a rather modest build just for development nothing too High end on the machine, however KDE and it's effects surely should run. I also use xfce so I switched to that and gave up on KDE 4.5

About a week after installing 11.04, I started noticing that my computer basically locks up after leaving it for many hours. When I come back, I cant get any programs to respond. I click on Firefox and it takes about one minute for it to finally respond. If I try to launch Konsole, it locks up too. But suddenly all programs start responding at the same time, after about one minute.
This is very frustrating and I just feel the problem is zeitgeist. Of course I am not sure because I cant even run System Monitor to check the problem since I cant run any apps for about a minute. By the time I run System Monitor everything is working again.

Using ubuntu 10.10 64 bit, last few days my desktop is not stable. Everytime my system becomes very slowwwwwwwww after login (after 5 mins, after 2 mins very random), sometimes it takes a while even to get to login screen. I checked System Monitor when this happens, i don't see high cpu usage/memory usage. Only thing i see is, when i shutdown my machine, it giving few errors about Virtualbox.

I'm new to Fedora/Linux trying it out because I'm becoming hacked off with Windows taking so much time to do anything. The problem I have is that every now and again the computer slows down so drastically that the mouse movements are jerky, response to clicks/key inputs take about 2-3 mins to get a response and the only solution is to press and hold the power button. I'm running a Packard Bell Dot M/U. It has mobile celeron 1.3GHz 64 bit, 3GB ram. Intel wi-fi, atheros LAN (i think), HDMI output. I believe that it is v similar to an Acer Aspire 1410 (but not 100% same).

Once in a while, my mouse pointer will just lock up and then when I try to kill the X server by pressing Ctrl + Alt + Backspace on my keyboard, it quits the desktop and it shows my wallpaper. It does not go back to the login screen. How do I fix this problem?

I'm running Slackware 13 with a custom kernel based off of 2.6.32.3. I tend to leave my system on 24/7, as well as my web browser. Originally it was Firefox and now it is Google's Chrome. Usually about a day of leaving the web browser open my HD activity spikes so high that I can barely do anything on the system until I kill the web browser. This has been happening with both Firefox AND Chrome! As soon as the browser processes are killed, the system returns back to normal.

I've got a Lenny system on a quad core system with 4GB of ram. Currently Linux www 2.6.26-2-amd64 #1 SMP Thu Nov 25 02:05:44 UTC 2010 x86_64
I've had it for a couple of years, and its been fine, very fast and reliable.
Lately, its got a problem: after its been running for a day or two, access using SSH, or TLS/HTTPS gets really slow. Painfully slow. A reboot returns the system to normal fast operation.
I can't think of anything that has changed, other than I got a new SSL cert and installed it.
The system is mostly a vanity domain server, with Apache HTTPD running a half dozen very low volume services. Its running bind9, mysql, and a few other things, nothing big, nothing that would load down a quad core with lots of ram. The disk is only 14% used.

I ran Karmic until last week, and noticed that it seemed to be getting slower. I was hoping a clean install of Lucid would fix that. it's worse. If I leave my machine running for a few hours, something begins dragging down the performance to a crawl.
System Monitor sometimes won't come up - launches an empty grey window. Other times, System Monitor reports that gnome-system-monitor is consuming 86-96% CPU. This is a dual-core Dell e6500 laptop with 4 Gigs of RAM, it should fly. Any ideas on troubleshooting this?

I have a newly installed Dell Optiplex 755 with Ubuntu 10.04 (64-bit) and I am having serious issues with network copying. Whenever I start rsync och scp with larger amounts of data my system becomes practically unresponsive (all types of apps grey out) until those processes are completed. Cpu stays at below 10% and I have lots of free memory and such .

I'll often run iceweasel for watching videos via flash (hulu, ....., et cetera) while working, in fedora I never noticed any performance problems, watching the video while using chrome for browsing, gedit for editing, et cetera, everything was responsive. Though, now on debian running iceweasel for the same purpose hogs memory and processor time, which slows down the responsiveness of the system as a whole, making it difficult to use other programs.I'm curious how I should go about troubleshooting this issue, and what diagnostics might help me find the solution.

I just installed Ubuntu 10.04 on my old Toshiba Satellite laptop. I'm dual booting with another Linux distro - ZenMini Everything works O.K. running Ubuntu but I can't restart the system with out it locking up. I have to power down completely from Ubuntu. I don't have any problem restarting with ZenMini so its obviously an Ubuntu problem.

At first I thought this was a scanner problem, but I've found that if I'm using the mouse while I'm scanning or sometimes just flipping back and forth with my usb kvm the keyboard and mouse become useless. If I'm scanning while I use the mouse, the system locks up. Here is what I'm seeing in /var/log/messages.

Using Ubuntu 10.04 or 10.10, have a router. Whether connected via ethernet or wifi, I'm experiencing a problem downloading files. Trying to download a linuxmint iso , my laptop will freeze up after 5 or 10 min. I have plenty of disk space, and screensaver off. I've googled quite a bit and can't get a clue. My desktop will freeze up too. I can't imagine what would cause this.

This laptop that I am trying to get Debian 5 working on is occasionally locking up during boot at "Activating Swap..." WTF could cause such a bizarre thing? The swap partition is just empty space. Activating must be nothing more than confirming it exists and mounting it.

Still having problems with the locked black screen freezing a couple of minutes in. I've done everything anyone has recommended on the other threads but nothing and it is driving me crazy. Please, does anyone have any ideas? I tried to install xfce4 but of course, screen froze and went black before I could fully download the software! I've tried the nomodeset but can't save it before doing a reboot (then went via terminal as quick as I could on start up to edit grub, but then... yes, it fell over and froze before I could hit save). So I'm giving this a lot of time I really don't have... such a shame I upgraded, 9.10 was working so well... alternatively,

System spec:
Core 2 Quad, Q6600, 2.4GHz OC'd to 3GHz
Asus Rampage Formula m/b
2x WD RE2 500GB HDDs ("linux boot" and "winxp boot")
1x Seagate Barracuda HDD ("boneyard")
4GB DDR2-800 RAM
Ubuntu 10.04 LTS
I'm having a really annoying problem with disc activity on my desktop system. Basically, if anything is writing a large amount of data to the hard drive (say, 10MB or over), the machine basically freezes solid. The mouse goes jittery (you move it and it takes a second then moves in one big leap).
For instance, if I try to image a USB hard drive to a file:
# dd if=/dev/sdh of=usbdrive_dump bs=1G
Effectively this works in two portions: it reads 1GB of data to RAM, then blats it out into a file. The machine is perfectly responsive while the USB drive is getting thrashed, but locks solid when the internal SATA drives are in use. Writing to USB HDDs doesn't seem to have the same effect -- I can copy 1GB files to/from them all day long and the machine is perfectly happy.

I just installed CentOS 5.5 on my machine and the installation appeared to complete successfully (it said it was successful). When I rebooted and tried to get into my new CentOS, my system completely locked up during the startup. According to the progress bar, it got stuck on the first-run configuration. I have not yet been able to boot into the OS. I am attempting to create a dual-boot system. I already have Windows XP installed on a separate hard drive. The GRUB loader works fine and I can choose either OS to boot into, it's just the CentOS won't finish booting. Windows is completely unaffected.Since I'm assuming the problem stems from the installation, I'll list the steps I followed.
1. Obtained the .iso image from a network drive at work (I am installing on my work machine). The image is dated May 17, 2010.
2. Burned the image to a DVD.
3. Booted from the DVD and chose to install using the graphical interface.
4. Checked the DVD. The installer verified that CentOS could be installed from it.
5. Picked my installation and keyboard languages.
6. Chose to create a custom layout for my partitions. On my second hard drive, I created the following partitions:
- Swap (8196MB, twice my system RAM)
- ext3 (100MB, mounted to /boot)
- ext3 (remaining drive space, mounted to /)
7. Picked my timezone (did not use UTC since Windows will handle setting the system time)
8. Set my root password. You don't get to know ;)
9. Did not choose to install any additional packages besides the KDE desktop. I wasn't sure what I'd need so I checked the option to customize later.
10. The installation than started and 15 minutes later, it told me it had succeeded and to remove the DVD and reboot.
11. Upon rebooting, I let the GRUB loader boot into CentOS (side note, I'd prefer if Windows was the default OS but that's something I should be able to Google on my own).
12. The startup looks like it's going fine until it gets to the first-run configuration, at which point the entire system locks up and requires a hard reboot. I've tried several times since and it always locks up at the same point.

The culprit is a Toshiba Samsung Storage Technology 222A CD/DVD RW drive, aka SH-S222A, sold under the Samsung brand. It occasionally locks up my entire system when I'm ripping an audio CD to a *.toc/*bin image with Brasero. I've had this happen with several different audio CDs, while ripping discs using both Imgburn under Windows XP and Brasero under Ubuntu 10.04. The display freezes completely, the mouse cursor doesn't move, and I can't get any response to keyboard input. Any sounds playing loop endlessly, repeating the last 0.5 sec or so before the cursor freeze. Meanwhile, the hard drive activity light stays on, but the optical drive light does not. I've let the system sit this way for several minutes, with no sign of change. To recover, I must press the system reset button.
I ripped the same discs without incident, using my other optical drive. It is a different brand, Lite-On, but otherwise similar to the Samsung drive: PATA interface, CD/DVD RW, etc. Anyone else have the Samsung SH-S222A? I'm wondering whether there is a bug in the drive's firmware, or I just have a defective drive. It works for other things. I can play audio CDs, access CD-ROMs, and rip audio CDs to individual tracks (rather than a disc image). I can also rip DVDs. Is there some way to recover my system when it locks up from drive misbehavior? I haven't found a way so far. I'm surprised that Ubuntu can be incapacitated so easily.
The SH-S222A has the most recent firmware revision, SB01. I tried to install the newer ID01 firmware from Samsung's website, but got a message that the installer couldn't find a "suitable" drive. I take that to mean that the ID01 firmware is meant for a slightly different variant of the -S222A, perhaps one only sold overseas. Yep, that's pretty much it. My drive's customer code is BEBE. Firmware ID01 is for drives with a different customer code.

I recently purchased a Quadro FX 4800 and tried to install it on Fedora 10. During the installation, Fedora didn't recognize my new graphics card and began installing the OS in text mode. I stopped the installation and tried to start over, this time I passed the following command: linux resolution=1024x768. I then proceeded with the installation, and again, I was posed with a text mode installation. I continued with the text mode install and when Fedora was done installing, I rebooted and system just locked up.
At this point I was frustrated, so I reinstalled my old 8800 graphics card and started a new install with something that worked in the past. When the install was done, I loaded the latest NVIDIA drivers and the rebooted. I reinstalled my new graphics card (Quadro FX 4800) then powered up my system. I thought everything was good to go and all of a sudden my system flickered and then locked up during the 'Anacron' testing phase. I then rebooted with the "Ctrl+Alt+Del" hotkeys, but my system always locks up during the 'Anacron' testing sequence. I am aware that the Quadro FX 4800 is a few months old, but how can I get it to work in linux? It has gotten so bad, that I had to resort to using MS Vista.
System specs:
Intel Core Duo Quad Core
4 gigs DDR2
SATA RAID 0
Mobo: 680i SLI
800WATT Power Supply

I've got a Puppy system running version 4.3.0 that I'm trying to get on the home network. I'm using a D-Link DWA-130 (H/W revision C), which has a Realtek RTL8192U chipset. I got the drivers off of D-Link's website, and they compiled and installed just fine, but when either a) I try to connect to the network, or b) while I'm browsing the web, the system locks up completely. No mouse, no keyboard, no Ctrl-Alt-Bksp to get out of X, nothing.
I'll outline my steps: Install Puppy using a "Full" HDD install (not "Frugal"). Copy the "devx_430.sfs" file (which I got from the Puppy website) from a thumb drive to the "my-documents" folder (although the exact location proabably doesn't matter). Mount it, cd to the mounted directory and execute "cp -a --remove-destination ./* /" and "sync". Copy the kernel source for 2.6.30.5 ("kernel_src-2.6.30.5-patched.sfs4.sfs") to the same directory. Mount it and execute the same commands as before. Copy the folder containing the RTL8192U drivers ("rtl8192u_linux_2.6.0006.1031.2008") to the root directory (i.e. "/"). cd to the folder in the terminal and run "make", "make install".Reboot the machine. Set up networking using the Puppy Internet Connection Wizard. HERE'S WHERE IT SCREWS UP: It connects, but after a while (e.g. just after logging into LQ through it, as a test) it freezes the entire system.
I have to do a hard reboot ("panic button"), then a soft reboot (for some odd reason the usb module won't load after a hard reboot, so the mouse won't work) to get the system working again, only to have it lock up again once it connects to the network.
Are these drivers broken? Outdated? Is there anything I can do to fix this? EDIT: I should add that this only occurs when the adapter is plugged in. If I boot the system with it unplugged, it works fine (probably because it never loads the kernel module).

I have an old PC in my basement that I decided to load Ubuntu onto a few months ago. I ran version 9 for a while and then recently upgraded to10.04.Unfortunately, I've been having issues with intermittent system crashes using both versions. Sometimes the computer will work fine for hours and other times it will crash 20 seconds after startup. I'll be able to provide much more information tonight when I get home but for now I wanted to plant the seed in the forum and see if anyone has any ideas.The computer will be working fine and then all of a sudden the screen will go black and then start blinking, switching between a blank screen and a blank screen with a bunch of tiny white squares/lines. When I restart, things seem okay again.

Running CentOS 5.5 on a Dell PowerEdge 710 with a mirrored RAID. System randomly reboots leading to MySQL table corruption as its not a graceful shutdown. Here is the output of the getinfo shell script [URL]. Some data has been obfuscated such as public ip addresses. Prior to posting this a full hardware diagnostic was run by the Data Centers support team which turned up nothing.

I am running the Nvidia driver. My system freezes randomly. I've had to reboot my system over 5 times today alone. When it freezes, everything is frozen, even the second hand on the analogue clock. One more issue, and I'm not sure if it's related, my stupid screen goes black after 5 minutes of no typing or mouse movement. This never happended when I first installed it. The issue just started within the last 3 weeks. Kpackage Kit is hidden. I was using it to do my automatic updates. Now I just use yum. between the time I first installed Fedora 12 and now, something has happened to my build to cause these issues.

I recently re-installed ubuntu to fix my freezing problem, but with no success. disc has no errors. I cleaned the disc and the cd drive, the cd burner has a problem installing while the dvd drive does fine. The computer is a HP Visualize X-class workstation with dual 1000mhz pentium 3s, 2 gigs ecc ram and a ATI AllinWonder 9700 pro @ 2x agp(wish was higher), on-board sound. So my problems are:
1) It randomly freezes within 24 hours regardless of who is logged in or if effects are on or what the load is. mouse is frozen too, completely unresponsive even ctrl alt f1.
2) My sound is screwy. its supported by alsa but i have to play with the volume to get sound and lots of times there are audio errors, it sounds like its robo-trippin. I have tried the sound guide.
3) Desktop effects only work with the user that logs in first. If I try to activate them when I switch users it searches for drivers then says it cant be enabled. not a priority.
Window xp works okay but the graphics drivers are giving me problems so i decide to do a dual boot.
I think I am going to put in a different video card. maybe its not all there, it got hot once when the fan died, put in a replacement and it worked but i see lines moving down the screen when there are blacks.
