> Key: AMQ-3451
> URL: https://issues.apache.org/jira/browse/AMQ-3451
> Project: ActiveMQ
> Issue Type: Bug
> Components: JMS client
> Affects Versions: 5.5.0
> Environment: jdk 1.6.0_23 for Linux 64 bit, Ubuntu 11.04
> Tomcat 6.0.32
> Spring 3.0.5
> Reporter: John Miller
> Labels: leak, resource
>
> 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 ?
