[vtp-dev] memory leak on deploy/undeploy cycle

[szabolcs jozsa <szabolcs.jozsa@xxxxxxxxxxx>]

Hi VTP Developers,

At working with VTP applications it turned out that there is a memory leak on the Tomcat6 Webserver when doing a deploy / undeploy cycle.

Started Tomcat with jConsole and tested : every Deployment/Undeployment costs about 6MB.


A "Test Application" with 3 Blocks: "Begin" - "Script" - "End".

Script contains only 1 entry: Log.info('Application started...');

Effect is the same - when deploy/undeploy this application ~15 times, following message occurs on /var/log/tomcat6/Catalina.out:

java.lang.OutOfMemoryError: PermGen space


Is this known, is there a workaround or any way to avoid the leak ?

Thanks in advance,
Szabolcs
