Hi all, Just watching for my first time the 'oom-killer' call in a CentOS 4.2 workstation. System was running normally but with high load of nice process, iow, rosetta and seti, others appart, nautilus, etc... i realized that after a night of standby running normally, the next moorning after few manual operations from X-session in local console, it started a massive swapping, this time not recovered as previously other time, finishing in a oom-killer call. Finally inspected the syslog and realize the oom-killer was called to leave the system stable having killed firefox-bin, 3 x rosetta, xmms and one nautilus. It's a PIII 800 Mhz, 40GB IDE, 512 Mb RAM, 1024 Swap space, up for 4 days. I'm not very xperienced in tunning the memmory system nor the swap system, help appreciated to avoid this memory 'trashing' situtation (14 virtual desktops openned at the same time). Is it a normal situation? Is it a correct protecction measure? It's due a low bandwitch IDE HD? how can i tune it to avoid this situations? is it a high load for this workstation? I think the oom-killer was called correctly to avoid the system collapsed, but i think there was a problem in the swapping subsystem or a memmory trashing situation to avoid. Help and hints appreciated, Attached you'll the oom-killer log, TIA J.J. -- Linux smarteyebox.stigmatedbrain.net 2.6.9-22.0.1.EL i686 GNU/Linux 11:55:01 up 1 day, 12:06, 9 users, load average: 1.20, 1.30, 1.57 --------------------------------------------------------- "Rome wasn't burned in a day.

set swappiness to zero. That will force the machine to use all physical ram before swapping for the most part. Also i have heard that xorg has a memory leak. I do not know if that has been addressed yet and that could be the cause of your issue.

Since the mid '90's, when I first used Linux (Slackware, from a fistful of floppies, on a 486 w/ 32 MB RAM & some tiny HDD), Linux has quietly become a memory PIG. That 1st install did have X running (FVWM IIRC) & it did run, including porting our code from SGI to Linux, which was the purpose of the work at that time (feasibility study, for NASA Langley). As I write this on my 933 MHz PIII, 1 GB RAM, 1 GB swap, SuSE 8.2, all stock, I observe from a 'free -m' in a shell: [wam at DARKSTAR, ~/FTP, 8:30:18am] 938 % free -m total used free shared buffers cached Mem: 1008 995 13 0 83 748 -/+ buffers/cache: 163 845 Swap: 1023 27 996 or 163 (!!!!!) MB being used, & for what ? 4 KDE destops, a total of 6 RXVT (supposedly light on RAM use) shells open, Mozilla as I write this, NFS & Samba daemons, & *THAT'S IT*. I don't know what to do about it (besides bitch to high heaven), but it is an appalling state of affairs, IMHO. There, I feel better now :-). As to this post, PC100 RAM is not too expensive these days, nothing speeds up swap like more RAM :-). Could you try another 512 MB of RAM ? -- William A.

part of returning from swap would be helped by reducing the kernel's tendency to swap..:) Andreas Rogge wrote:> Am Mittwoch, den 14.12.2005, 12:13 +0100 schrieb J.J.Garcia: > >>Finally inspected the syslog and realize the oom-killer was called to leave the >>system stable having killed firefox-bin, 3 x rosetta, xmms and one nautilus. >> > > > Hello J.J., > > I think it was firefox who ate all your memory and the situation > returned to normal when it got killed. > I'm sometimes running into problems with firefox.

Yes i start thinking so, it's almost the same situation and experienced b4 somtimes burning the cpu others eating the remaining available RAM but not arriving to oom-killer call just this time, Thx everybody for pointing. [sm0ketst at smarteyebox ~]$ firefox -v Mozilla Firefox 1.0.7, Copyright (c) 1998 - 2005 mozilla.org [sm0ketst at smarteyebox ~]$ rpm -q firefox firefox-1.0.7-1.4.1.centos4 But just a dummy question, can a started process like this launched from the user space become as big eater of memmory without being stopped/killed b4 by the kernel? i mean, im i having i as a normal user this facility of stashing the system? Maybe it is a non-sense question due im not expert with the kernel core, but i start thinking im doing something wrong if launching the web browser in my normal unprivileged user account im able to drive the system to swap limits forcing this trap to occur... but trying to be possitive it's not a complain...
