Hello Niall -- it looks like you have plenty of options for clearing
out those pesky PID files, but no one has addressed this part of your
email. Anything beyond a hobby site needs some sort of monitoring for
situations just like this. At RailsConf, Ezra specifically mentioned
using monit (which I currently use) to monitor one's individual
mongrel processes. If that sounds like too much work, an excellent
alternative is the free Heartbeat website (http://
heartbeat.highgroove.com/) which allows you to monitor multiple
application URLs and email yourself when things go awry. I'd
encourage you to go sign up for heartbeat and see if using monit is
feasible for you. No financial connection to either one, just a very
satisfied user.
