I’m on a VPS running CentOS. I startup my server with:

mongrel\_rails start -d -p 3000 -e production

and it runs for a while. But later I receive ‘502 Bad Gateway’ errors  
implying my mongrel has crapped out. So in the console I do this:

[prompt]# mongrel\_rails start -d -p 3000 -e production

\*\* !!! PID file log/mongrel.pid already exists. Mongrel could be  
running already. Check your log/mongrel.log for errors.  
\*\* !!! Exiting with error. You must stop mongrel and clear the .pid  
before I’ll attempt a start.

[prompt]# mongrel\_rails stop

Sending TERM to Mongrel at PID 1298…Process does not exist. Not  
running.  
Done.

So I have to manually delete log/mongrel.pid to be able to restart the  
service. log/mongrel.log shows no errors. How can I:

1. find out why mongrel is failing
2. stop mongrel\_rails from failing?
3. make it restart automatically
