We have the problem of a few php files that occaisionally just wont die , for whatever reason.
We have tried everything to isolate the issue, but with no success.
We came across the following perl script which we are running as a cron, but sometimes it still doesn't kill the pid's.
ps -lef | grep "nobody" | grep httpd | perl -ane '($h,$m,$s) = split /:/,$F; kill + 9, $F if ($m > 2);'
Our server runs on centos 5.7 "nobody" is how we define apache process users.
Bascially, the script should be killing anything that is > 2 minutes old.
