I have a series of scripts that are being killed ($? says exit code is 137, which implies a kill -9 scenario). I need to know what process killed them. Is there a way to find out this information?

I don't believe that there's any way to retrieve the pid of the process that sends the kill, at least from within another process. The signal is sent via a kernel interrupt, and as far as I know, it's only the kernel that knows which process sent it.
That being said, if you're comfortable with patching the kernel to find this out, you might take a look at this: patching the kernel to log signals

Exit code 137 references a time out signal.
Read this page on exit codes and signals
I'd also suggest looking for the OOM issue in the /var/log/messages folder.

From your link: `... exit code 137 means that the job received a signal 9 ...`; this is not a time out signal. – Glen Solsberry Mar 28 '11 at 15:49

forgive me that was under the hypernews section. Have you checked out the /var/log/messages ? – Split71 Mar 28 '11 at 16:58

Yes, and regarding any kills, it is empty. – Glen Solsberry Mar 28 '11 at 17:25
