How to reproduce the bug?
==========================
       
    1) Install MQ3.0.1sp1 on your test machine. For this download bits from
http://jpgserv.red.iplanet.com/JMQ.builds/releases/FCS-3.0.1SP1/bundles/

Install doc is located @
http://docs.sun.com/source/816-6453-10/index.html
http://docs.sun.com/source/817-0355-10/index.html
http://docs.sun.com/source/817-0354-10/index.html

2) Start two MQ brokers in cluster mode as follows.

imqbrokerd -tty -name broker1 -port 7676 -cluster :7777 (on terminal #1)
imqbrokerd -tty -name broker2 -port 7777 -cluster :7676 (on terminal #2)

3) Download Longevity testsuite (Longevity2.jar) from http://jpgserv.red.iplanet.com/imq_qa
to your test location.
    
4) Add Longevity2.jar, "$IMQ_ROOT/lib/imq.jar" and "$IMQ_ROOT/lib/jms.jar" to CLASSPATH

5) start MQ Comsumer from broker2
       java -cp $CLASSPATH -DimqBrokerHostName=localhost -DimqBrokerHostPort=7777 Longevity.LongevityConsumer

6) Start MQ Producer from broker1
       java -cp $CLASSPATH -DimqBrokerHostName=localhost -DimqBrokerHostPort=7676 Longevity.LongevityProducer 2 2 25

For more info on test document please refer to
http://jpgserv.red.iplanet.com/imq_qa/testcases/Longevity_Testsuite.html
http://jpgserv.red.iplanet.com/imq_qa/testcases/Longevity-Howto.html

The bug shows up in the Broker (server) vm after couple of hours....
