Exception while long haul tests

[Shamli <sh...@aztecsoft.com>]

I am doing long haul tests, and i'm sending 30 messages per second for a
duration of 1 hour. After exceuting 14000 messages i got this exception in
catalina.out. What could be causing this exception?
I m using ActiveMQ 4.0.1.

Exception in thread "ActiveMQ Session Task" java.lang.OutOfMemoryError:

You'll have to run it under a profiler and send us a memory snapshot.
I prefer yourkit or jprofiler since I've got a copy.
