I have a webserver that had it's Apache killed this morning. The box
itself had been stable for several years, as well as the Apache
instance. The error that I saw in /var/log/messages was something along
the following:
"pid 1234 (httpd), uid 100, was killed: out of swap space"
So I went to check what was eating up the swap,
The problem itself was tracked down fairly easily, someone had added a
shelt script to cron (/home/user/foo.sh) and had mistakenly put the full
path to the script into the script itself -- essentially creating a
forkbomb.
But while I was in the middle of debugging this and noticed that line
from the logfile, I spent more time than necessary trying to figure out
exactly how much swap/memory was being used, and who was using it.
