Claus Ibsen commented on AMQ-3451:
----------------------------------
Okay AMQ-4026 is now committed, so we have a better API for shutting down
thread pools. Will work on getting the patches in the codebase, so the JMS
Client work well in Tomcat when re-deploying apps.
A fully embedded ActiveMQ broker in Tomcat has a number of more pools and other
parts in the works, eg such as JMX and whatnot that can cause a bit pain, eg to
ensure all JMX stuff is properly unregistered and whatnot.
First priority is the JMS client though.

> 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 ?
