Check that a process hasn't crashed/quit

I found information on cron here http://www.vmts.net/crontab.htm. I know a little about cron, but not enough to have it check a process. Maybe you could make a script that will do that, then have cron run the script. I hope this helps

There are tools like

They work great for me on a Debian server I run in a colo (qmail, tinydns), but I never tried it on Mac OS X.

Depending on the daemon in question, it might not be good enough to just make sure it runs, it should still provide the service it's supposed to.

qmail is pretty much bulletproof, if it runs, it works.
Apache for example has modes of failure where it will still run, but stops to deliver pages.

A Nagios-like solution that checks for the service and takes action as you script it if the test fails, is probably the best if you really care for continued service.

If you just want to do it the simple, brute force way, look at this old thread:

Excellent, got it all sorted out now!Many thanks!

I just ran into a gotcha. On older Macs running tcsh (e.g. 10.2.x) make sure you write:
ps axwww filename

It turns out that the terminal may not be wide enough.
