Gary Tully resolved AMQ-6702.
-----------------------------
Resolution: Fixed
The dead letter strategy has an message audit that is enabled by default. This
prevents duplicate messages from being added to the configured DLQ. From
5.15.0, the limits of the audit can configured via the
maxProducersToAudit and maxAuditDepth attributes. The audit can be disabled
using enableAudit="false"
> Allow dead letter strategy audit configuration

>
> When the default shared dead letter strategy is used with composite queues or
> durable subs or virtual topics and messages expire - the dlq gets lots of
> requests to store duplicates. The audit on the strategy traps most of these
> duplicate add attempts but that audit is not configurable so it is possible
> the some get through which may be trapped by the message store or cursor on
> subsequent dispatch.
> Allowing the audit to be configured past the default parameters allows
> duplicates to be stopped at source.
