Summary: Memory leak

Initial Comment:
We try to use OpenJMS for communication within a 
database query system. Now we ran into a memory 
problem (OutOfMemory error on the server side). We 
contact the server via RMI.

I have reproduced this memory problem with server and 
client on the same machine (WinXP) using the example 
console programs. I processed following steps:
1) Started server with startup.bat
2) Put a Thread.sleep(1000); to the beginning of the 
onMessage() method of 
file\src\examples\openjms\examples\client\console\Simple
Consumer.java
3) Started runconsumer -topic mytopic
4) Started runpublisher -topic bla -count 100000
5) Observe servers process in the task manager

If the memory consumption of the servers process 
exceeds 87MByte, I get following exception:
javax.jms.JMSException: Failed to sendMessage  
java.rmi.UnmarshalException: Error unmarshaling return 
header; nested exception is:java.io.EOFException

org.exolab.jms.client.rmi.RmiJmsSessionStub.sendMessag

at org.exolab.jms.client.JmsTopicPublisher.publish
(JmsTopicPublisher.java:144)
at openjms.examples.client.console.SimplePublisher.main
(SimplePublisher.java:127)

Additional in the Java console of the server I see 
sometimes a java.lang.OutOfMemoryError

What can I do to prevent this errors? I played around 
with the GarbageCollectionConfiguration settings but it 
doesn't solved my problems...

Thanks in advance
Frank
