Hello, I’m using Tomcat 6.0.29. Tomcat manager application is enabled. Version of installed Java is 1.6 update 18. Operating systems used to test this are Windows 7 and Ubuntu 9.1.
There is one Spring web application that is deployed on Tomcat. Deployed application have some threads that are running in background. Then try to un-deploy application by using Tomcat Manager. Application WAR file and folder where WAR file is unpacked are removed, but I get this error in logs: *Aug 12, 2010 2:35:23 PM org.apache.catalina.loader.WebappClassLoader clearReferencesThreads SEVERE: The web application [] appears to have started a thread named [scheduler_Worker-6] but has failed to stop it. This is very likely to create a memory leak.* When I try to deploy new version of application (also by using Tomcat Manager) I get the “Out of memory” exception. I try to change definition of following listener: *<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" gcDaemonProtection="false" />* And I also try to add following parameters in context.xml: * <Context antiJARLocking="true" antiResourceLocking="true"> * Can I configure Tomcat to kill all treads when application is undeployed? Thanks in advance. Ivan
