Subject java.net.ConnectException: Connection refused: connect, while running performance test on AMQ 5.2/5.3
Date Tue, 09 Feb 2010 14:43:16 GMT

Hello, 

I'm running performance test on top of AMQ. The test is a servlet which : 
1.create connection, session and sender on (queue/topic) 
2.send 20 messages 
3.create connection, session and receiver on (queue/topic) 
4.receive the same 20 messages 
5.close both connections 
The load on the servlet is 20 users. 
Test is running OK for some time and start to fail with this exception: 

java.lang.RuntimeException: javax.jms.JMSException: Could not connect to
broker URL: tcp://localhost:61616. Reason: java.net.ConnectException:
