Why does my Perl script exit with 137?

Is there a way to eliminate a warning (exit code 137) in perl? I am running a Perl script on linux within another shell script. This Perl script exits with a warning and exit code 137. I could not pinpoint what exit code 137 stands for.

What is the best way to avoid this warning? I tried "no warnings" in the script and I have an exit 0 at the end of my Perl script as well.

I got the same error code 137 from an ANT script. Looking at /var/log/messages, I understand it's out of memory error.

I just ran into the same exit code 137 when launching a python script. It turns out to be the OOM killer kicking in, sending SIGKILL to python interpreter. If it's the same cause, you can find oom msgs in /var/log/messages

I suspect the exit warning is printed out by the shell which called the perl program, not by the perl program itself, so "no warnings" in the perl code won't help you. exit code 137 means it was killed with a SIGKILL signal.

137=128+9, which means some other process has sent you a signal 9, which is SIGKILL. I.e. the other script kills yours, that's what it looks like.
