Re: [ruby-75] How do you clean stale PID files?

Steve -

I don't know how Mongrel deals with these, but I would imagine you could kill the process and delete the file.  If you're on Unix/Linux or OS X, you could:

ps aux | grep mongrel

This will show any running processes containing the name "mongrel".  One of them will be the grep itself.  Hopefully there will be another one including "3031".  You can terminate it like this:

kill [masked]

If Mongrel still won't start, it may be necessary to delete the PID file.  Try to find the file and manually delete it.  If you can't find it, open a terminal window and do:

find / -name mongrel.3031.pid 2>/dev/null

This might take a while, but should find it.

Good luck,
Keith

I know this is a simple question for you guys, but I am not a dev and my developer is not in yet.

I am trying to restart mongrels by running this: mongrel_rails cluster::start -C /home/urbis/apps/forum/config/mongrel_cluster.yml

I am getting this error:

** !!! PID file log/mongrel.3031.pid already exists.  Mongrel could be running already.  Check your log/mongrel.3031.log for errors.
** !!! Exiting with error.  You must stop mongrel and clear the .pid before I'll attempt a start.

I know there is away to clear stale PID files, but not sure how to do it.  Any advice would be great.

Thanks!

Steve
