It won't help me to increase the permgen size, because the client does a lot<br>

I tried this tomcat flags, and it does nothing:<br>
-XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled<br>
-XX:+CMSClassUnloadingEnabled -XX:+UseParNewGC<br>
I tried set the flag : PermGenThreshold=0, like other people suggested in<br>

any help? it's production issue...<br>
