I've changed mine to do the -r 5and to send an alert if it is not running.
as long as -r 5 does what it is suppose to do everything will be ok
if it fails at least I'll know about is - this is where monit is useful, no
matter how smart/capable an erlang app is "suppose" to be, I'd like to know
if it goes down :)
