Unexpected duplicate message alerts in a two-broker mesh

Solution Verified - Updated -

Issue

Unexpected warnings about duplicate messages are seen in the broker's logs, in a two-broker, fully-connected mesh. These messages appear when there are consumers for the same queue on different brokers, and in the absence of any failure condition that might be expected to cause a retransmission.

Environment

  • Red Hat AMQ
    • 6.3

This problem does not affect AMQ 7, since its mesh implementation is completely different.
