I my experience, a crashing app *will* crash again. Doing an autorestart
cycle is a sure way to kill a server *and* obscure history enough you
won't be able to say why it crashed in the first place.
Much better to provide an health check that can be plugged into a
general purpose monitoring app like nagios (or if you're really that
desesperate, schedule regular reboots in the system cron).
