What is the underlying cause of a PermGen OutOfMemoryError in JBoss?

I am running JBoss AS 4.2.2 in my development environment, and this occurs after redeploying my web application a large number of times.

Christian Vest Hansen's blog gives JVM options that help a lot, but do not solve the problem completely:

-XX:+UseConcMarkSweepGC
-XX:+CMSPermGenSweepingEnabled
-XX:+CMSClassUnloadingEnabled
-XX:MaxPermSize=128m

Trips to the server room can mean extended periods away from the comforts of home, or at least your desk. Especially if it is an off-site hosting facility.

What should you take with you, apart from a warm sweater for places with good air-conditioning?
