Description

When tomcat crashes with a segmentation fault, it doesn't have any automatic way
of starting back up. In a single server/single tomcat situation, this causes
users to get an internal server error if there's an apache front end, or just be
unable to connect if it's standalone, until the administrator notices and starts
it back up. Eliminating the segfault is the best solution, but sometimes not
possible (for example we have a DB2 driver that crashes the JVM about once every
48 hours). What I would like to have is watchdog functionality which starts
tomcat, then restarts it if it dies with a SIGSEGV (and probably logs the error
and/or notifies someone). I think jsvc would be able to deal with this pretty
easily.
