Where a CentOS 5.3 installation on a server randomly restarts. The problem is that I am not able to find a viable solution. I have updated the system to the latest available kernel, but to no avail...
The output I see in /var/log/messages when the restart occurs is very similar everytime:
...remainder of system boot logs
It's been freezing on me like you wouldn't believe today, and I think it has something to do with the load put on the CPU by various sites. The trouble is, I need to access a few of these sites to do my work. WordPress is one of them. I've had to restart the computer five times via SysRq keys since when these freezes happen, I can't Ctrl-Alt-Backspace out of it (even with zap enabled) and I can't bring up a terminal or Alt-F2 to kill process. I can't switch processes, windows, or anything. Firefox just sits there and laughs at me as I threaten to bust the screen in half.
And the real funny thing is, people actually say this is a better browser than IE. I never had these problems on Windows.What can I do to stop this? Do I just have to switch to another browser?
since the launch of Natty I have been having stupid reboots randomly happening, no warning or otherwise occurs just a full reboot. This only seems to happen when browsing (FF or Chrome) and I have disabled every one of my addons and done the usual checks - baffled I am...So I had this with the upgrade I did on launch day, so naturally I did a full wipe and fresh install. Same situation - personally I cannot deal with this happening all the time so I went back with another full wipe to Maverick and all has been well.
Anyway I thought leaving this a few weeks would mean the community would have seen and squashed dealbreaker bugs so I re-installed yesterday, today the crashes came back again so I throw myself to your wisdom - anyone else seen this, know where I should be looking for ideas? My logfiles don't show anything prior to the reboot as an error.In all honesty I do not want to go back to maverick and cannot believe that Ubuntu have released such a bug riddled distro.
I have centos 5 installed. and i use a firefox 3.6 browser on it. the problem is that whenever i open some sites like facebook, or easyxdm.com, or some others, the screen just gets hung up and the os either restarts or remains hung up.
View 2 Replies View RelatedI'm running CentOS 5.3 x86_64 on my laptop (dell vostro 1400, core2duo, 3GB RAM, intel 3945ABG wireless, nvidia video and LAN). The problem is that some times (like 15-20% of times) I shutdown the laptop, I get a kernel panic related always to the wireless kernel module (I haven't been able to get screenshot or anything). I'm using the latest centosplus kernel. I never get these panics with the standard CentOS kernel, however the standard kernel doesn't light the wireless led, and that annoys me a lot. Therefore I'm forced to use centosplus kernel. The question is not how to solve this (i know I've not given enough details) but what to do to diagnose better the cause of the panic and then correct it.
View 3 Replies View RelatedI recently installed CentOS 5.3 on a Dell PowerEdge 1800 server that used to have Microsoft Windows SBS 2003 on it. Everything seemed to be going fine until a few days ago. Here's the sum of it all...
- System seems to randomly hang, at which it becomes unavailable on the network (can't be pinged, monitor won't come back on, and you can't wake it up... have to reboot, the scroll lock and caps lock keys flash at the same time)
- Received this error message...
Uhhuh. NMI received for unknown reason a0.
You probably have a hardware problem with your RAM chips.
Dazed and confused, but trying to continue.
...it doesn't crash at this point though. I ran memtest86 twice and did not experience any problems. I updated the BIOS to the newest version, which contained a few bug fixes, but still experienced the same problems
I configured a Postfix Server to relay the messages to an Exchange Server. To keep it simple I configured all my users locally and I setup local .forward files in their home folders, specifying their local Exchange address.
Everything seemed to work fine (for years now), until I upgraded postfix in October, 23rd 2010.
Alas, lately I noticed that, since then, even if I just realized it now, sometimes the server seems not to use the .forward file and tries to use the local delivery using cyrus, which does not find a local mail folder (obviously, since I never created them as I didn�t want to) and replies to the sender with a "550-Mailbox unknown" error. Today I enabled the "-v" mode for "local" in master.cf the debugging the problem a bit better, to see what's the problem.
If I was sure about the problem being the postfix version (2.3.3, which is way too old now!), I'd give it a try and substitute it with the latest 2.8.2 (even if the server is a production server and is almost untouchable).
Following the error and my main.cf and master.cf setup files:
I'm about to ask may be a better question to ask a certain vendor with "Red" in their name, but I thought I'd ask it here anyway. I'm looking into various methods of doing patch management (scaling up to 300 or so servers, eventually), and one of my thoughts was to simply create separate yum repositories (e.g., testing, staging, production) and roll updates through each one of them as they go from being tested to being ready to roll out on to live systems (using yum via cron on each system to completely automate the process).
That being said, something I've noticed in going about prototyping this solution is that some services (e.g., Dovecot) automatically restart after updating, whereas others (e.g., Apache) do not. I would think a more logical policy would be all-or-none, but perhaps I'm missing something here that would explain the logic of not restarting Apache and any other daemons that get installed. My thinking is if you're updating a system, you should probably be in a maintenance window anyway, so services should be expected to go down and come back up, if an update necessitates it.
I know I could always grab the source RPM file and alter the SPEC file to restart, but I'm genuinely curious as to why things are setup the way they are, and while I realize Red Hat is the source of this, I wouldn't be surprised if there was plenty of insight here into the matter.
I am new to CENTOS (5.2) and more importantly new to linux. Any time I try to gcc compile something, it always throws random errors. I yum installed development-tools which is what I have seen other threads suggest but that did not solve the issue. I still get the same errors. I cannot find a common error among the many things I have attempted to compile.
Here is my most recent file for an example made when trying to compile up-imapproxy :

View 3 Replies View RelatedI have several systems experiencing this issue, but the "worst case" system at the moment is a system where there are 2 dual-port PCI-X e1000 cards, and two on-board e1000e PCI-express card.What happens is maddening. If the /etc/sysconfig/hwconf is removed, and kudzu is not run, and the 6 interfaces each have a corresponding script:
/etc/sysconfig/network-script/ifcfg-eth0
/etc/sysconfig/network-script/ifcfg-eth1
/etc/sysconfig/network-script/ifcfg-eth2[code]...
Now what happens defies explanation. The only way I can be sure to make the e1000e first-listed-in-pci-order e1000e device always eth0 is to remake the initrd and add e1000e to the initrd.If I do not do that, eth0 might be the onboard night, it can also be the first port on either of the dual port cards.So eth0, eth2 and eth4 all take turns being eth0. This was not an issue in the EL-5.1 timeframe. This is certainly new to the EL-5.2 timeframe and thus far is not possible to control because the system does not load eth0's driver alias in order, and the enumeration of the PCI devices causes what seems to be random labeling of the first interface.
This is a particular problem in that identical hardware systems will come up with different eth0 interfaces , and on a single system, without the /etc/sysconfig/hwconf (which calls "eth0" something different from what was originally in the /etc/sysconfig/network-scripts/ifcfg-eth0 HWADDR directive).I need as little auto-magic as possible, I can live with PCI-bus order and driver load order is the order ethernet devices appear in, I cannot use the software in a state where what is "eth0" is randomly determined and the only way I can nail it down is to run kudzu, generate a hwconf AND brand the network interfaces in the network-scripts with HWADDR. I've been using EL since 6.2 and this is the first time I've ever encountered a situation where the enumeration rules (which are ancient at this point) over-ridden by something.
Version-Release number of selected component (if applicable): EL-5.2 series.The random enumeration of PCI devices and the subsequent assigning of eth0 to a random NIC is not on every reboot, and does not seem tied to a power off scenario vs a simple reset or warm reboot. Over the course of 0 reboots , eth0 should have moved between 2-3 times.Packages that seem relevant.

View 7 Replies View RelatedI am hosting a home server to make developing stuff easier. And because I don't need my server all day and night I automatically start and shut it down. For starting I use Wake-On-Lan (etherwake) and to shut it down I am using my RaspberryPi. Finally I have a problem doing that: When I use WOL to start my home server it works perfect. But when I try to shut it down, I have to do that twice. After the first shutdown it restarts automatically even when no WOL-Package is sent.
I am using Debian 8.1 Mate as os.
My stop script is:
Code: Select allsshpass -p<password> ssh root@server.home.lan shutdown -h now
and I start it with
Code: Select allsudo etherwake <mac address>
both times using a cron job on my RPi.
I've come across a problem just recently where my laptop will restart after I shut it down from within Debian. I've looked into my BIOS for anything that might trigger this, but could not find anything. I run Debian Testing 64-bit on a Dell Inspiron 17R laptop.
View 6 Replies View RelatedAbout two weeks ago I installed ubuntu 9.10 desktop with a dualboot to my windows 7, which was already on there. everything went fine, but I couldn't configure my wireless to work, so after a few days I gave it a rest and basically forgot about; I just stuck with windows. anyways, yesterday night I installed a program called solidworks on my system. I woke up this morning, turned on my computer, and this is what happened-
it turns on for about 5 seconds, but when it hits "grub loading", after about half a second it restarts. it's basically an infinite loop, until i throw in a cd or hit f8, but I don't know what to do with either of those options, so I'm kind of stuck.
I'm posting this in the ubuntu forums because I have NO idea what's wrong with it, and no idea of where to start. I've got both installation disks, but I don't know what to do when I put them in. I've got an intel pentium 4 processor, and like i said, i've got a dualboot with windows 7 and ubuntu 9.10.
I'm currently using ubuntu desktop 9.10 (without desktop - I've removed packages) as OS on my server.But there's going on some strange thing ... There are about 8 users, and the thing is they many times user rar or some other disk-demanding programs. What I've noticed is that sometimes server will go with load over 20 (I know that's not good ...) and it will come down in few minutes and everything is OK, but sometimes it just restarts itself. I would like to disable that so it won't restart

But now I have the problem:
Every time I insert the Windows 7 DVD the pc says "Please press any key to boot up from CD/DVD" (as normal), but when I press the "any" key, the PC does absolutely nothing and just restarts.
Not to long ago I used the same DVD on another laptop for an equal upgrade (XP to 7) that went flawless.
My booting set-up is correct, cleaned the disc 500 times now, nothing out of the ordinairy done to my boot-screen or the BIOS... And as far as I know, no blue screen of death when installing the upgrade.
I haven't got a clue what I have to do.
When I suspend my system everything goes well but when I restart it boots up again and start from the beginning...and I don't have my programs open then...
View 3 Replies View Relatedthis problem has really been getting at me, I can't figure it out at all. About a week ago, I came home from school and found that my computer was shut down (usually I leave it on), I started it up in Windows 7 and a Malware Bytes scan said it found a virus "clipb.exe". Well, I decided to remove it, and when booting up in windows it BSOD's saying IRQL_NOT_LESS_OR_EQUAL immediately at the login screen. Same result in safe mode and "last known configuration". Well, I decided to reformat just because I didn't want to go through too much trouble, and about a week later (today) it came back. I have no clue how, I was away from my computer. But the difference between this time and last time is, I can't start ubuntu at all. period. It gets to grub, and then after that gets to a black screen with no progress. The only thing I can do is ctrl+alt+dlt which restarts the computer.

View 9 Replies View Relatedmy X server restarts and boots me to the log screen when I start programs. I recently took the Nvidia card out of my computer and put in an ATI card. This is of course after uninstalling the Nvidia drivers through the restricted drivers interface. This worked out very well but eventually I went back to Nvidia. I removed the ATI drivers put in the Nvidia card and installed/selected the Nvidia drivers just as I did when I did this the other way previously. However now when I start just about any program the entire X server boots me back to the login screen.
View 2 Replies View RelatedMy laptop restarts itself frequently - full restart back through the bios screen to the bootloader, not just logging-out. It happens in Ubuntu 11.04 (32 bit and 64 bit), the Gnome 3 live CD from [URL] (the Fedora based one, run from a USB stick) and even from the GRUB bootloader menu. I have tried two different harddrives and two sets of RAM (all combinations) and the restarts still occur. They even happen when the hard drive is removed and Ubuntu 11.04 is booted from USB. Windows XP Media Center is also installed on the laptop too but the restarts have never happened when in Windows (even though they can happen in the bootloader!).
The memtest86 GRUB menu entry loads the blue screen with the title and memory info etc. but it seems to stop there and I don't think it's actually doing any tests, so I haven't been able to do a memory test. In Windows I have not installed any wireless network or 4-in-1 card reader drivers (among others probably), which is a possible reason why it does not restart in Windows, although I don't think GRUB has drivers for either of these devices either. My laptop is an Acer Aspire 5630 with the following hardware:
CPU: Intel Core 2 5500 (1.66Ghz)
Memory: 2GiB DDR2
Graphics: Intel 945 (integrated)
Audio: Intel HD audio with Realtek codec
Wireless: Intel PRO/Wireless 3945ABG [Golan]
It does seem that sometimes the restarts are caused by touching the keyboard (i.e. they happen exactly when I hit a key) but they also sometimes occur when I am not even touching the computer at all.
I this problem where my laptop hangs up or suddenly restarts. Currently Iam using Fedora 15 but I had this problem when I was using fedora 13. I upgraded to 15 thinking that may be its been resolved in 15.

I checked /var/log/messages for possible clues but I have not been able to figure it out. Below is the output of /var/log/messages files just before the laptop freezes or restarts.. so far the below output has been consistent with the event...

My dads' hard drive went up a while back. So we got him a new one and installed Ubuntu 9.10 instead of windows. All was going well until About two weeks ago. The system restarts randomly. Not when anyone is doing anything in particular. Sometimes when we are using firefox, sometimes just sitting on the desktop, and never after any certain amount of time.Some times its after five minutes, some times after several hours. It's not a full out crash, the window for shutdown/switch user/restart comes up out of nowhere. When we close the window, it shows back up pretty quickly, but then the computer will just crash. While restarting, half of the time the computer won't make it past the bios screen before restarting again,and will continue the bios restarting cycle until the computer is unplugged. By the way, the system is a dell dimension E310 from 2005 with all of the original hardware minus hard drive inside, so if it is a hardware issue that wouldn't surprise me. Also, just one time after the restart I received the message "fsck from util-linux-ng 2.16" , if that helps at all.
View 6 Replies View RelatedI'm on Fedora 13 (64 bit) and using tvtime (latest version 1.0.2-13.fc13 installed via yum) which I've managed to get to work with my old WinTV card (bt878 chipset I think) by having it start with its mixer-device set to "hw:0/Line" (the WinTV card outputs the sound via a cable to the Line In socket of the soundcard).
This all works (I can control the volume in tvtime using the left and right keys) except that the volume resets to zero every time I restart. tvtime remembers all my other settings (and the previous volume is even saved in its config file) so I think the issue is related to ALSA/PulseAudio resetting the appropriate mixer (Line In on the internal sound card).
However, I can't find which mixer tvtime is accessing. In 'Sound Preferences', changing the Master Volume affects the sound from tvtime, but none of the other mixers seem to be related to it (and tvtime doesn't appear on the 'Applications' list). I've also tried finding it in alsamixer, which gives me a choice of 'default' (PulseAudio), 'HDA Intel' (the internal sound card) and 'Brooktree Bt878' (the TV capture card) and again the 'Master' and 'Front' mixers do affect the sound, but are not the mixer that tvtime is accessing.
I know this is a very specific and minor thing, but it's a bit annoying seeing as I've got everything else set up near-perfectly.
Or alternately, as a workaround, is there an easy way of creating a script to lanuch tvtime and send some volume up commands (right arrow key) the first time it is run after a restart (but not the times after that)?
I have a USB keyboard and everytime I start up openSUSE, it's turned NumLock back off. Is there any way to keep it turned on by default?
View 4 Replies View RelatedRecently, I updated the kernel to the latest version and also installed Ruby and the Passenger module for Apache. The server was fine for a few days.However, today, it's been restarting randomly (usually a minute after I can log in).I tried booting with recover mode so I could view the logs for a longer period of time, but that caused it to restart before even allowing me to log in. Now, all boot modes will just cause the server to restart right after the GRUB messages appear.Our server setup complicates things. We have a RAID-1 mirroring for the /boot partition and a RAID-5 (software) for the / partition
