One thing we use here is a script that keeps an eye on the qrunners.

They've died on us for some reason once or twice, so we use this  
script to notify us of the problem.  We run it from cron.

# check-qrunner
# see if mailman's qrunners appear to be running and squawk if
# they're not.

if ps axw | grep -v grep | grep -v check-qrunner | grep qrunner >/dev/ 
null; then :; # life is good
         # life is bad.  try to restart the qrunners, and tell someone
         /usr/share/mailman/bin/mailmanctl -s start
         worked="did not work";
         if ps axw | grep -v grep | grep qrunner >/dev/null; then
         echo "Hi.  I am /usr/local/bin/check-qrunners on `hostname`.

The Mailman qrunners seem to have died.  It appears that my
attempt to restart them $worked." | mail -s "mailman qrunners"
