From time to time messages duplication occurs in topic.
Presumably after restart of arbitrary broker.
In the same time no errors in logs.
Just this warning

I know that connection between brokers could be duplex.
But we had many other problems with duplex that is why duplex="false" now.
And my question. Is activeMQ designed to guarantee that message is delivered only once?
Is this feature or bug?
