How do I know if the Linux server killed my process and which process it killed?
Solution 1:
It's quite possibly OOM killer, killed your process. You may be able to find out what when etc by looking in the logs.
egrep -i 'killed process' /var/log/messages
The actual log file varies by distribution so it could also be /var/log/syslog or even
egrep -i -r 'killed process' /var/log
