Out Of Memory ActiveMQ 4.1

I face the OOM errors running on 4.1 , IBM JRE 1.5 on a linux box
This has been reported in JIRA:

https://issues.apache.org/activemq/browse/AMQ-1205

Any clue where this might be happening ?

If you're worried about that, run the broker as a separate JVM.

Thanks Sandeep....
Im more concerned about why this is happening, since I start AMQ 4.1.1
within Geronimo, rather than using it as a stand-alone app. As a result, I
want to make sure that my App server doesn't crash, as it now does !!!

Try the following:

1. in conf/activemq.xml, uncomment the <memoryManager> block and set the
<usageManager> to "512 MB" or some such higher memory value.

2. edit bin/activemq and set the ACTIVEMQ_OPTS with "-Xmx512M" or such
higher number.

These two settings should buy you more memory space for large number of
messages, but doesn't eliminate the exception, if you have many unacked
messages in queues or durable subscribers.
