Undeploying Showcase from Tomcat6/7 can cause memory leak --------------------------------------------------------- Key: RF-13071 URL: https://issues.jboss.org/browse/RF-13071 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-push/poll, showcase Affects Versions: 4.1.0.Final, 5.0.0.Alpha1 Reporter: Juraj Húska Priority: Minor Labels: memory_leak, performance Fix For: 5-Tracking When undeploying showcase from Tomcat 6/7 then following log is present on the server console: {code} SEVERE: The web application [/richfaces-showcase-tomcat6] appears to have started a thread named [Thread-0 (group:HornetQ-client-factory-threads-1831192424-1080990297)] but has failed to stop it. This is very likely to create a memory leak. {code} There is lot of such logs, just the _Thread-counter_ is changing. * 11 such logs just with showcase deploying and then right after undeploying * bit more when after deploying playing a little bit with {{r:push}} IMHO it is not just warning. I am experiencing {{Out of Memory}} issues when testing on Tomcat. I need to use quite big {{Perm Gen}} and {{Heap size}}
