Resolution: Fixed
Fix Version/s: 5.4.0
resolved in r932342
ensuring suppressed durable deliveries are acked allows the message to be
removed such that it does not get redelivered on recovery (startup)
> Durable Subscriptions have messages replayed (duplicate messages) after
> network broker restart

> Durable subs in a network of brokers can experience duplicate deliveries when
> a broker restarts.
> The problem lies in duplicate suppression and missing durable acks. Give two
> brokers, each networked together and with a durable consumer on each. A
> message produced to One gets delivered locally and forwarded to the other
> broker where it gets delivered. The redelivery back to the originator is
> suppressed by a filter that sees the broker path bread crumb. However this
> suppressed message is not acked so the broker on restart sees an outstanding
> durable message for the networked broker and recovers the topic subscription,
> delivering duplicates.
> differences in the store implementation, a store per durable sub or a shared
> sub store mean the issue surfaces differently.
