The default PermGen space is 128M, and while not many things use PermGen, Tomcat eats a lot of it, so it's common to run out when re-deploying webapps, or deploying apps such as JPA-based apps that also consume PermGen.

You should be able to ease the pain by creating a file named "setenv.sh" (or setenv.bat, for Windows) in the TOMCAT_HOME/bin directory. Put this line into it:

You can adjust the Xms and Xmx if you like - I pulled this from a major server which uses more RAM than average.
