How to keep FastCGI processes alive

October 30th, 2005

I have the following CRON entries for one of my sites: 

1
2
3

39 * * * * killall -9 dispatch.fcgi >/dev/null 2>&1
0,4,8,12,16,20,24,28,32,36,40,44,48,52,56 * * * * \
curl http://www.weputlightsup.com/ >/dev/null 2>&1

What does this do ? The first entry kills all of my FastCGI processes at 39 minutes past the hour. The second one pings a specific URL to ensure the FastCGI processes are always up and running, every four minutes.

I am certainly not the first to mention this technique, see View processes, grep out by user and then kill all their PIDs.

Seems strange though that I couldn’t find much references to this technique while Googling around.

Anyway, I hope this helps someone.
