As far as I understand the kernel, oom is called when the system has no
memory pages left, and MUST get one to continue normal (ie. kernel)
processing. The kernel just do not have the time to execute some
user-space code, it MUST get free pages where they are (and hence, kill
immediately some innocent process).
This condition should not occur without using overcommit. Are you sure
you are not using overcommit ? (cat /proc/sys/vm/overcommit_memory)
To dasable it:
echo 0 > /proc/sys/vm/overcommit_memory
Overcommit is quite dangerous on production systems, because it leads to
oom kills on heavy loads (at least, this is what I experienced).
