Hey, I know this doesn't give you a direct answer. But I found this article quite interesting on the topic of undeploying an application and classes being left loaded, which in turn leaves the classloader.

Hi: I have been trying to track down a memory leak in my struts 1.3.10 web app. I am using tomcat 6.0.26 which has a leak detector button in the manager app. After basically gutting my app to a start up page, it occurred to me that I should just see if the struts-blank web app has a memory leak. Well, when I deploy and undeploy the struts-blank web app and check for memory leaks, it has a memory leak. If I do this a couple of times, take a heap dump and use eclipse mat (memory analysis tool) plug in, I see several WebAppClassLoaders. When I look for duplicate classes I see a bunch of org.apache.commons.beanutils classes in these WebAppClassLoaders. I can't really go any farther in characterizing the leak since I don't understand enough about classloaders. This seems like a bug to me. Any ideas would be appreciated? mas --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
