Subject Re: ActiveMQ Causing OutOfMemoryError After Service Deployment in ServiceMix
Date Tue, 24 Jul 2007 06:21:57 GMT

Your problem have the same symptoms that the one I've notified as 
AMQ-1319 if you're using activemq 4.1.x or a lower version. 
DestinationMapNode is not correctly erasing all the references 
(specifically the 'anyNode' nodes) of the map and so, leaking also Topic 
references and all the related stuff.

If this is the same problem, you shoudn't suffer it under 5.0 or under 
4.1 with the patch I've attached to AMQ-1319.
