Subject Re: Out of memory exception in ActiveMQ
Date Wed, 27 Aug 2008 11:12:03 GMT
Try increase your heap; as a broker and mule server and JMS client is
gonna use up RAM.

To reduce the memory overhead of the JMS client you can reduce the prefetch...

the out of the box broker config should be fine but if you're really
short of RAM you can reduce the usageManager settings
