What kernel version? I had something similar and oom-killer was no help
in identifying the culprit.
This is no help. :-(
Linux compost 2.6.12-1-386 #1 Tue Sep 27 12:41:08 JST 2005 i586 GNU/Linux
the machine had been up for 61 days (I checked a few hours before it failed)
with no problems and is running Debian testing.
Having a closer look at the logs I notice that the first time it killed
postmaster but after that it just seemed to repeatedly kill the apache2
I see what oom-killer is trying to do but I can't believe for one minute that
I was running low on memory (the machine is running quite a few processes but
never thrashes the disk). A typical top looks like this:
top - 11:14:29 up 2:19, 4 users, load average: 0.04, 0.11, 0.12
Tasks: 143 total, 1 running, 142 sleeping, 0 stopped, 0 zombie
Cpu(s): 4.6% us, 1.3% sy, 0.0% ni, 93.7% id, 0.0% wa, 0.0% hi, 0.3% si
Mem: 321792k total, 308852k used, 12940k free, 15320k buffers
Swap: 393584k total, 8340k used, 385244k free, 55168k cached
Which is a little odd because I thought that machine had 768 MB of ram not the
300 odd that is being reported. Maybe I removed some :o) it's been so long
since I opened that box I can't remember.
Well, again this is no help, but anyway:
What does 'cat /proc/meminfo'show?
In response to my oom-killer I started my sensor apps to show Free
Memory. That doesn't get you any closer because that value floats from
the high end to about 10-15MB on later kernels and 3MB on earlier kernels.
Do you remember what BIOS shows on memory installed?
