Non-persistent messages are load balanced via multiple routes
regardless of how many active sessions exist on the source broker.
There is certainly no logic to do this, and I don't see the same
behaviour myself. Messages on a queue are not shared out between
subscribers in strict round-robin, subscribers compete to pull them
off the queue as fast as they can. Over a large set of messages this
usually results in a relatively 'fair' allocation. It is possible that
the durability can alter the timings in some cases such that the
distribution appears to be different
Are you perhaps running with worker-threads == 1 or on a single core
machine. It may be an artefact of threading if that is the case.
