    rabbitmq mq messagebroker

I am guessing I need to 1. change the listening port 2. change the appdata folder (C:\Users\MyUser\AppData\Roaming) 3. change the ui plugin port so I can view all instances. 4. remove the service and run from cli Has anyone tried it?

Despite that this behavior is undefined according to the JMS spec (last time I looked anyway), they expect a sort of round-robin / load-balancing behavior.
