What killed my process and why?

by

My application runs as a background process on Linux. It is currently started at the command line in a Terminal window.

Recently a user was executing the application for a while and it died mysteriously. The text:

Killed

was on the terminal. This happened two times. I asked if someone at a different Terminal used the kill command to kill the process? No.

Under what conditions would Linux decide to kill my process? I believe the shell displayed “killed” because the process died after receiving the kill(9) signal. If Linux sent the kill signal should there be a message in a system log somewhere that explains why it was killed?

Try:

dmesg -T| grep -E -i -B100 'killed process'

Where -B100 signifies the number of lines before the kill happened.

Omit -T on Mac OS.
