Also bear in mind that each consumer by default will prefetch 150 messages, so this is probably what is happening: 1) Create consumer. 2) 150 messages get prefetched. 3) Receive one of the messages 4) Forget about the consumer 5) Go to step 1 So in 20 iterations, probably, 20 * 150 = 3000 messages will be in the consumers. If you can provide some valid JMS code that demonstrates a problem will be happy to investigate further. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3984162#...
