Re: Tracking all signals how to

[Mahmoud Hanafi]

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?

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.
