Hello, tomcat version: 8.0.22 java: jdk1.8.0_05 server: Amazon Linux AMI
I get the following warning message in my catalina log when I undeploy a web application: *WARNING [ContainerBackgroundProcessor[StandardEngine[Catalina]]] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web application [ROOT##002] appears to have started a thread named [pool-2-thread-1] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread* As you can see, for some reason, I don't get a stack trace of the thread. Therefore, I have no idea how to debug this warning. This particular warning was generated when tomcat detected an unused version and undeployed it (I set undeployOldVersions="true"). Does anyone know how I can debug this warning. How can I know more about this thread? I used the manager app and clicked "find leaks" but it said that there were none. (Can someone also explain why I have to be cautious when using this feature on production environments). Thank you
