Not sure whether you mean that GC ignores PermGen, or just that in your 
particular situation, GC is not clearing out PermGen of what you think are dead 
classes.

The former is definitely untrue, although that rumor has wandered around the 
Internet for many years.

You should definitely move up to a current JVM - 6u23 if possible.  Also, the 
latest versions of Tomcat 6.0 include memory leak detection and correction for 
several typical application abuses, so try that as well.
