Hi,
this is normal behaviour when using frameworks that create classes on the
fly - each loaded class takes a part of the permanent heap space (which does
not expand and doesn't reclaim memory after old classes unload). Both
Hibernate (entities) and Stripes-Reload (action beans) redefine classes when
necessary. What you can do is passing the JVM an -XX:MaxPermSize=256m option
(replacing 256 with the number of MBs you want to assign) - for Tomcat, you
change *CATALINA_HOME*/bin/setenv.sh (or .bat) to do so.
