             Summary: Allow dead letter strategy audit configuration
                 Key: AMQ-6702
                 URL: https://issues.apache.org/jira/browse/AMQ-6702
             Project: ActiveMQ
          Issue Type: Improvement
          Components: Broker
    Affects Versions: 5.14.0
            Reporter: Gary Tully
            Assignee: Gary Tully
             Fix For: 5.15.0


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.
