Nothing in the logs to indicate what the problem might be. Seems to happen
when it processes a 404 error sometimes.

I have one instance supervised with runit, but supervision doesn't help since
the mongrel doesn't crash, it just hangs. I now have a 10 minute cron that
checks on it and restarts it if it's unresponsive, and it's doing so a few
times an hour now, which is disturbing.

It's happening a lot to me right now. No --debug option to mongrel?
