I’ve come across a problem which has similar sounding symptoms & have done a bit more investigation (no resolution yet though).
My problem is that when a network connector failed back to the remote broker specified by the "priorityBackup" uri, the remote broker doesn't seem to recognise that the connection is from another broker & doesn't check the producerID. Because of this, it rejects messages with duplicate sequences (even though the producerID is different).
