RE: OpenJMS crashing! Help!

1. How many messages per second are you sending?
2. How many producers?
3  How many consumers?
4. maxThreads is far too high. The server will create 1000
   threads which will kill performance. The default value is 10.
5. The destinationCacheSize is the no. of messages per topic/queue.
   Consider reducing this if you have a lot of destinations.
