Same issue, except I'm using ActiveMQ 5.5. And even with consumer.prefetchSize=1, I still have messages for all group IDs being sent to consumers on only one of the JVMs.
Even more intriguing, if I let the whole thing run for a longish period, I *do* see some or all of the message groups switching over to a different JVM, but this is not very repeatable, and I can't discern a pattern to it. I've tried everything in this chain. What else can I try? -- View this message in context: http://activemq.2283324.n4.nabble.com/Load-balancing-message-groups-tp2349471p3465452.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
