CentOS 5 Networking :: NFS Freeze And GAM_SERVER Crash?
Feb 4, 2010
I've installed Centos 5 on 2 serveurs.The first one export the file system with NFS.The second one use amd to automount the filesystem with the link/net/@IP/Shared/folder/On the client side, I mean the second server, there is some logs into the messages system telling us the the process gam_server as crashed (segfault)On the first one, sometime, NFS Freeze, and nothing is available. This need a Hard reboot of the server in that case.
I seem to be having a problem on the new Kernel (2.6.35-23) with the system randomly freezing.
I have installed a number of things in recent days leading up to this problem, but when i boot with the old kernel i don't seem to have any issues. From this i am guessing its the new kernel.
The freezing seems (although i am not sure) to be worse when Rhythmbox is running. When it happens everything freezes, the playing song skips, replaying the same one second of music over and over. All the hotkeys stop and the mouse cursor stops responding.
I have seen people talking about system logs to look at system crashes but i don't know how to show those. I also doubt my ability to interpret them.
Today im experiencing many freezing issues with my office desktop running lucid amd64.
Every application i run, seem to randomly freeze and then crash.. i dont understand wy, yesterday the pc worked as usual.
I was using kernel .38, i tryed to switch back to .32, but nothing change;
This is my apt history (some packages has been updated yesterday):
Code:
I dont see any packages that can cause this error. The freezes seem to be related to the hard disk: if i try to copy/download large files, the freezes happen instantly; but i've tryed Smart test from disk utility, and GSmart from a live cd: the hard disk seem to be ok. Even memtest doesnt report any error.
I have a fresh installation from the demo ISO image of F14 running on an Acer TravelMate 4200. The system is a Dual Boot with win Vista. Windows Vista runs without any problems but when using F14 a kernal crash constantly occurs and it then hard freezes or hangs and the machine needs to be cold booted. There is nothing in particular that I am doing either, the problem happens when the machine is idol or when I am working in various apps.
The F14 system is completely up to date running kernel version 2.6.35.13-91.fc14.i686. The following error below is from the automatic bug reporting tool and I have reported this using the tool:

I previously had my bt878 capture card setup with Ubuntu 10.04 and it worked fine with Zoneminder. However, after having done a clean install of Ubuntu 10.04, the card causes Ubuntu to freeze whenever I attempt to view the image in a viewing program (happens in tvtime, Cheese and Zoneminder)I have added bttv and bt878 into /etc/modprobe.d/options like before, and have also added options bttv card=77 tuner=-1 into bttv.conf in the same directory (had to create bttv.conf)The freeze causes the whole computer to lock up, and nothing on the keyboard or mouse is responsive, and involes having to do a hard restart.The only difference I can see from before, is that I have installed all of the latest updates with Update Manager, so maybe a new update is causing these problems?Output of dmesg � grep bttv

I have one desktop PC I'd like to use as a jukebox. It's installed in the basement as a black box, with only SSH access, and it has got a minimal CentOS 5.3 install with MPD and NCMPC. It's connected to the hi-fi in the basement, so I can stream music to it when I'm downstairs. Since I didn't want to use cables everywhere, I bought a PCI wireless card, with a RT2561 chip.
Until recently this card worked OK with Linux. Recent kernel version even have out-of-the-box support for it, except of course you still have to download the firmware from the Ralinktech website.
I gave the thing a static IP configuration by editing /etc/sysconfig/network-scripts/ifcfg-wlan0, interface went up fine, I can ping the machine and SSH into it OK. Now the only problem is, when I do a shutdown -h now, the machine "hangs" while trying to bring wlan0 down. (In case you wonder: I temporarily attached a monitor to it, since wanting to know what goes on while shutting down in an SSH session is a chicken-and-egg situation :)). I actually have to hard-reboot it (by pressing RESET).
Since the last Versions of openSUSE 11.3 and now with openSUSE 11.4 with KR46, I've a blocking system sometimes with all memory used (especially swap). KDE Hangs only the mouse works. The Harddisk is 100% used (HDD LED is always on). This blocking is about 5 minutes and 30 minutes. In this time only very minimum work is going on. If I switch with <ctrl>+<shift>+<F2> to the tty, a lock in needs 3 times (the password request is after the time out). top shows only 5% load with "gam_server" (first or secound entry -> most system load).

I have a not yet encountered issue on my server tonight, this is weird as it seems it sounds like an old issue, but I didn't noticed that before (I always have a "task monitor" or "top" running somewhere)[URL]gam_server is taking "full cpu" (or 100% of one of my core),without anything special done from me, but the latest update to current...Does anybody had this behavior too ?I understand there are some way to sort that, but I was curious why is that thing is appearing in a 'vanilla' configuration... Isn't it weird somehow ?
PS/ I had nfs shares in my fstab, that I had to remove because as they're not always present, that was blocking for several minutes at boot time... It was not a big issue as those shares were not vital, yet it's unpleasant. The only thing I saw on the changelog was a "nfs-utils" update, maybe it's related ? Maybe the default "timeout" have been changed ?
I have some trouble with my hp workstation xw4400 with an ATI FireGL 3300 and the X-Server. There was no problem with the graphical install routine and the graphical boot works fine. But when the system changes into the login-screen, then it results in a black screen and a more or less frozen system.
I've just install a new Virtual Machine with Centos 5.4 on a server running VMWare Server 2.0. I need to install Acronis 10 Linux Agent (latest version). My kernel version is 2.6.18-164.11.1.el5. I already install Acronis Agent. Compile kernel for module snapapi26 0.7.47.When I reboot machine it starts correctly, but when I connect to it from my Acronis Console running on host machine, Centos freeze and keyboard led start blinking.
i would like to upgrade my centos 5.3 with the oldest update from repository. (about 224 update)I would like to update all the system but keep freezed php and mysql.
I have a problem with the VMware Workstation 6.5.2 build-156735 on CentOS 5.3. When I start a VM then, after 10-20 minutes the machine and VMware Workstation freeze. The mysterious thing was, after the freeze a large of folders from my two partitons were lost. ( I have two partitons on a NVIDIA Raid,configured with dmraid.) But the partitons still here, I can see them and they are mounted. Its very mysterious.
I have installed the VM's to a folder on my raid. When I killed the processes and restart VMware Workstation I cant start a VM.
VMware says that CentOS 5.3 are supported for the VMware Workstation 6.5.2 build-156735.
I'm installing Centos 5.5 32 bit and after the reboot and during the install the keyboard and mouse freeze up. Why? No way to correct except reboot and it freezes again.
I have my DNS configure in 2 zones. 1 internal, and the other external. DNS is chrooted under /var/named/chroot amd has been operating without any problems for well over 2 years now. I have recently run cross the problem shown in the subject line. When I try to freeze the internal dehnert.com zone with the following command...rndc freeze dehnert.com IN internal
I get the error...
I have been running the command as root, and with iptables turned off, so there is no firewall to restricting access. (the system sits behind a firewall) I have been searching the forums all over, but I havent run across what might be causing me to have root denied access. If anyone has seen any problem like this, please point me in the right direction so I can iron this out.
When running Matlab (7.10.0.499 (R2010a), 64-bit (glnxa64)) on CentOS 5.4 using vnc, the Xvnc chrashes and this is logged in syslog:

CentOS is up to date as of beginning this week. Doing a quick net check suggests HW-problem ( HP DL380 G6), but I've tested both memory and cpu(s) without errors. We also had the same problem on Scientific Linux 5.4.
I'm a long time user of CentOS 5 w/KDE 3.5. I have always had this problem to various degrees no matter what installation of CentOS 5 I'm currently on. This same hardware does not exhibit the same symptoms with another OS.The problem is I regularly have many konsole instances open. I alt-tab between them frequently. Inevitably a random alt-tab will freeze the keyboard and the mouse won't be able to click anything although I can move the mouse cursor around. I can't type anything. It seems to have some sort of timeout and it always come back to responsiveness.
I alleviated this problem (I think) by switching keyboards, installing the nvidia driver instead of the nv driver, shutting down all non-essential services.I have seen these symptoms on every system I have installed CentOS 5 where KDE 3.5 was also installed. Very different hardware setups each time.Has anyone else run into similar symptoms?I'm surprised that it's just CentOS 5 w/KDE 3.5 that exhibits this behaviour on the same hardware where other operating systems (gentoo, suse, etc.) did not exhibit these symptoms.
I have a Ubuntu 10.04 fresh installation on my HP laptop. Installation successful and boot OK. But the desktop randomly freeze. During freeze(about 15s each time), all programs are not responsive. Sometimes I can switch program by click, but program seems locked. How can I know which module cause the freeze?
I am using CentOS5.2 and gnome 2.16, sometimes (not very often) when I open something and close it by clicking the CROSS on the top-right corner. The application crash and I lose all control (no keyboard anymore), I have to reboot the system by reset the machine. What's going on?
Yesterday, when I logon as root and run service setup, after I uncheck a sevice in the list and then start it, I click the CROSS on the top-right corner of the window, it popup a window (in the background) to ask me to save it or not, but then I total lose the control, no mouse, no keyboard. I try to reset the machine many times, but everytime when I repeat the same operation, it crash again. Seems that if I don't close it, everything would be fine!!!!
when open an pdf and close the tab/windows at firefox I get the error at syslog: kernel: npviewer.bin[21396]: segfault at 0000001000000000 rip 00000030abe2646c rsp 00007fffb0978ca0 error 4
My exercise below is to check if glxgears crashes xorg of CentOS5.4 with Intel GM965 Chipset. Apparently I don't have luck in this case. Since the exercise failed, it means I will still stick to CentOS 5.2 (residing on a different partition) for a while, even though CentOS5.2 crashes glxgears too. After "yum upgrade" (done after moving all repos in /etc/yum.repos.d to elsewhere except CentOS-Base.repo and CentOS-Media.repo), I ran glxgears that consistently crashes CentOS5.2 xorg, an issue that upset me quite a bit.
During upgrade, I saw a line "grubby fatal error : unable to find a suitable template". I guess the my grub.conf is too confusing for the installer, but that is not big deal, I just used the kernel number 2.6.18-164 where it is applicable. Even this this new update, glxgears still crash the xorg (the screen froze and then a new login screen reappears). With this I am sure the 3D application might still crash the xorg from time to time. (I can still revert to CentOS5.2 with a tar file, but I am still thinking to just upgrade to Centos5.3 but I don't know how.)
I using only Livecd CentOS 5.4 and my system crash in day about ~3-5 times , so I tired and want to know why this happen. (before I used live-cd 5.3 about 3 weeks and this problem still was. info : Linux livecd. localdomain 2.6.18-164.el5 #1 SMP Thu Sep 3 03:33:56 EDT 2009 i686 athlon i386 GNU/Linux.I load system perfect and If I just browsing then I will have crash after 5 hours latter , but if I install wine , xmms,lame,xmms-mp3,k3b-mp3,flash-plugin and after installing software I will look movies from internet , or lisining music on xmms mp3 format - my system UPTIME max will be ~30 minutes or less..And I want to ask, or in Live-cd I can start Firewall ? Becouse I think it's not started and then I try to ENABLE its looks like not responding.
I've faced the problem with server freeze on heavy write.
System
CentOS 5.5 x64_86 with latest updates and kernel (2.6.18-194.32.1). Also tried 2.6.18-194.26.1 and 2.6.37-2 from ELRepo with the same results. CPU: Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz Memory: 3 x 2Gb DDR3. HDDs: 2 x Western Digital WDC WD1002FBYS-02A6B0
this message is a bit long but I've been pulling my hair for 2 days now. I am installing Centos 5.3 on a Dell Powerege R610, x86_64 flavour. That part goes well. next is testing backup & restore. I've tried MondoArchive, that I used on other OS, but it fails to remount the LVM correctly, and disk formatting fails. Now, I am trying another way: boot with centos 5.3 i386 live cd, take the disks online, cpio to a usb file everything but: /tmp /proc /boot /dev /etc/fstab /etc/mtab
then, reinstall a fresh centos to erase the disk (crash simulation) and to simulate the initial restore I would do after a crash. From there, I go again with the livecd, mount r/w the logical volume, cpio -i all my files, and reboot. It sort of goes well. system reboots correctly - it loads all my drivers (even asterisk & dahdi and the T1/E1 card light goes green...), starts KDE, but from there I get an infamous error message preventing me to log in "Your session only lasted less than 10 seconds" - looking in the details, i get this message "could not exe /etc/X11/xinit/XSession default' - but I dont think X11 has so much to do with it...
When I go to a text console (ctrl alt f1), and try to log, no luck either - and no time to see why. I've modified initrd to level 1 - there I get the single user prompt, that's ok - but init 3 brings me to a screen where I cant log (either with root or a user) - there is a clear difference between an incorrect password and a failed login - the later, as soon as I enter the password, I return to a login prompt Now my questions. 1/ how can I make a "system backup" of Centos 5.3 x64 -ie after a crash, I want an image tha t I will restore and bring back OS + Applications (data can be backed up separately) 2/ what is wrong with my restore thru livecd ? why cant I log into the system ?
I'd rather not switch back to SM 1.1.18 as 2.0 is so much better. I've had this same crash on at least one other page too (not on centos.org this time).
I installed the last CentOS x86 with Gnome on an IBM Netfinity 5600 Server but after the install, at the reboot, when X start i got many colors bars with the X cursor of the mouse in center of the screen and the server is frozen.I looked if the good display driver was load, and it all right.Booting at runlevel 3, but nothing more.. same problem when i start the configuration or X.By the way, i'm new here so please, don't judge me for my knowledge.Usually I was using Slackware)Here the specs for the server:-2x PIII 800 CPU-1024Mb RAM-6x SCSI HDD 18.5Gb in RAID 5-Graphic card: S3 Trio3D 4MbIs the card too low in RAM to run X?
I recently had to power off my Centos 5.5 box (ungraceful shutdown). When it came back up, three apps popped up: "Welcome to the Gnome Help Browser" (which is Yelp). In another desktop, Konqueror is waiting for a login. This happens every time I restart my system. I haven't been able to figure out how to stop this. Every time I've shut down my system since I had to bring it down hard, it's been gracefully and neither of those apps was running.
I am running matlab 2010b on centOS5.6. Matlab opened without any error either in the computer terminal or in VNCSERVER. While running bench (of matlab) the session or the vncserver are crashing.In some cases the bench run for the first time without any problems, however it will crash the session or the vncserver on the 2-3 runs of the same code.
After CentOS5.3 install to /sdb7 partition (on 2nd HD) and using Ubuntu Grub(on 1st HD mbr) to boot CentOS, I get "memory for crash kernel 0x0 to 0x0 not within permissible range" as soon as CentOS starts. I have 2G of ram. The message is on every boot. I've had several other linuxes on that partition without such an error message. Otherwise the OS starts fine. Is the message of concern/import?
it says this at start of boot:memory for crash kernell (00x00 'or something like that') not within permisiable rangeotherwise no problems for now, ewerything runs fine.
