> Consider a set-up with two brokers clustered together and redistribution enabled and a address with about a dozen multicast subscription queues bound to it. If a consumer of one of those subscriptions goes offline, messages will begin to build up in the queue (as expected). When the consumer comes back online, whatever broker it attaches to first will have messages redistributed from the other broker in the cluster. When this redistribution happens the other multicast queues receive some of those redistributed messages (although not all of them) even though they had already received them previously.
