Hi there,
i just opened an 800mb movie file with pico/nano, waited for the OOM, and here
it is, have a look:
Apr 26 16:10:45 codeman kernel: Out of Memory: Killed process 19789 (apache).
Apr 26 16:10:46 codeman kernel: Out of Memory: Killed process 27828 (apache).
Apr 26 16:10:48 codeman kernel: Out of Memory: Killed process 14554 (apache).
Apr 26 16:10:50 codeman kernel: Out of Memory: Killed process 19893 (apache).
Apr 26 16:10:52 codeman kernel: Out of Memory: Killed process 32036 (apache).
Apr 26 16:10:54 codeman kernel: Out of Memory: Killed process 8370 (apache).
Apr 26 16:10:56 codeman kernel: Out of Memory: Killed process 680 (mysqld).
Apr 26 16:10:56 codeman kernel: Out of Memory: Killed process 7638 (mysqld).
Apr 26 16:10:56 codeman kernel: Out of Memory: Killed process 26780 (mysqld).
Apr 26 16:10:56 codeman kernel: Out of Memory: Killed process 26038 (mysqld).
Apr 26 16:11:01 codeman kernel: Out of Memory: Killed process 3914 (pico).
Apr 26 16:11:01 codeman kernel: VM: killing process pico
Apr 26 16:11:04 codeman kernel: Out of Memory: Killed process 20471 (squid).
So, you guess, apache, mysqld, squid and the causer pico are killed, but NO,
ONLY, and i mean ONLY pico was killed, all the other Processes listed above
are running fine, accepting connections, short: works fine!!
And yes, its reproduceable !!
The above is a kernel without rmap!
I also tried this with rmap enabled kernel, no OOM Messages appears, but the
system freezes. It does NOT accept any input on keyboard, mouse or via the
network (e.g ping, traceroute, telnet to smtp port etc.). Also, if the system
does not accept any input, the harddisk is doing something, i've waited ~ 45
minutes, system was still not accepting anything, harddisk was doing
anything. This was rmap12h with 2.4.18.
Kinda strange, isn't it?! :-)
I like it, cause only the causer get killed, but why those syslog messages?!
Syslogd lies like a trooper ;)

Try with -AA (splitted vm33), latest ist 2.4.19pre7aa2.
It works for "ages".

Dieter
BTW Have anyone a copy of these nice "test.c" for the OOM, handy?

I guess it should be better to OOM here...?

I second the suggestion :)

I'm probably talking nonsense here, but apache, mysql and squid; all of
them run there services with several processes. Could it be that the OOM
Killer only killed a couple of childs and not the parent of them all?
