[rules-users] permgen leak

i'm using drools 5.5.0, after the rules deployment, (associate DRL's with the KnowladBase and compile them) my permgen grows to 500m, and also if i undeploy, the permgen doesn't cleaned up. (only if i restart the server) It won't help me to increase the permgen size, because the client does a lot of heavy deployment, and can be in the maximum size by 3-4 deployments. I tried this tomcat flags, and it does nothing: -XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled -XX:+UseParNewGC I tried set the flag : PermGenThreshold=0, like other people suggested in your forums and it doesn't help. any help? it's production issue... -- View this message in context: http://drools.46999.n3.nabble.com/permgen-leak-tp4027038.html Sent from the Drools: User forum mailing list archive at Nabble.com.
