I have downloaded the application from https://docs.google.com/open?id=0B-ZFcczN9qxYZmh5dDdoMFVCUkE, and analyzed the heap dump.

I don't see any memory leaks related to threads, the only memory leak with your web application is  AMQ-3959

> 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 ?
