Ok, I think it's a problem that is signaled with Topic and conduitSubscriptions set to false (what I need for selectors and queue load balancing)
I think it's the A's embedded broker which sees 2 consumers on B's broker and decides to send 2 messages because conduitSubscription is false. It's strange. I will add a mechanism that deletes the doubles, but I think that it should be integrated in network of broker usual usage.
