Subject [jira] [Commented] (AMQ-3451) Tomcat 6.0.32 complains that ActiveMQ 5.5 doesn't shutdown a thread
Date Fri, 07 Sep 2012 12:01:10 GMT

    [ https://issues.apache.org/jira/browse/AMQ-3451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13450546#comment-13450546
] 

Claus Ibsen commented on AMQ-3451:
----------------------------------

Okay got the JMS client leak fixed and committed to trunk. No leaks reported by Tomcat, and
the WebappClassLoader did not have any strong references to any classes anymore. So seems
we can fully undeploy/redeploy without leaks now.

> Every time when restarting web application in Tomcat Manager I get messages:
> SEVERE: The web application [/sms] appears to have started a thread named [ActiveMQ Task-3]
but has failed to stop it. This is very likely to create a memory leak.
> With every restart PermGen space is increased and finally i got OutOfMemory error for
PermGen space.
> I use Spring DefaultMessageListenerContainer, and it's shutdown method closes properly
receivers threads. What is "ActiveMQ Task-3" thread and how to close it properly ?
