Kalle, Chris, thanks for your answers. Unfortunately the problem is not related to webapp reloading even restarting the Tomcat service leads to out of PermGen in a few days, PermGen itself is quite large and I already use UseConcMarkSweepGC. Down here you can read the java settings :
-Djava.awt.headless=true -Dfile.encoding=ISO-8859-1 -Xms512m -Xmx2048m -XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/tomcat6 -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled The cause of the space consumption seems to be the presence of a lot of classes of this type org.apache.tapestry.enhance.ClassFactoryClassLoader It seems that the more request the application serves the more PermGen increases and that's led me to think that the page pool is never cleaned up or at least not well cleanedup.
