Sergey commented on AMQ-3451:
-----------------------------

You can't call org.apache.activemq.thread.DefaultThreadPools#shutdown when ActiveMQ libraries are in Tomcat shared lib, because calling that method will shutdown the shared thread pool, and  all other web application deployed to the same Tomcat will be unable to send any JMS messages.

> 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 ?
