I've begun using a gadget called Monit (http://mmonit.com/monit/) to watch Tomcat, and to SMS me and restart it when it crashes. Monit can trigger on a number of different conditions, and I'm hoping to be able to automatically manage other failure modes (such as spinning at 100% when PermGen is exhausted, grrr!) -- Mark H.
