We have random nodes experience killing of most daemons( syslog, ssh,
cron, etc). All these daemons report getting a sigkill or sigterm.

My question.... Is there a way to log all signals and the originator
pid/proc name.

Thanks,
Mahmoud

Did you already have a look in the kernel messages to make sure it's
not an OOM problem ? I do not know of any Linux software that sends
random signals to random processes.

Yes I have verified that it was the OOM killer. We always get lots of
messages in the conole log when the oom killer starts. This is a very odd
problem as there are no logs showing what is doing the killing.

May I can wrap the kill() systemcall?
