ActiveMQ Task going into a out of memory state

[konijeti <ra...@customerxps.com>]

Hi,

I am using ActiveMQ 5.2.0 as messaging server and tomcat as Application
server on Solaris OS.
After 7 days of continuous running, the ActiveMQ task threads are going into
a out of memory state on web server and there are no ERROR or EXCEPTION logs
in ActiveMQ server side. The WebApplication has both ActiveMQ clients and
server.

It appears to be some memory leak either in application or in ActiveMQ. what
does the thread "ActiveMQ task" do? does this thread execute application
logic? 
could you please throw pointers in narrowing down my issue? 

Thanks in Advance,
Ram
