Gary Tully reopened AMQ-3576:
-----------------------------


The default true for auditNetworkProducers needs more consideration. 
networkConnector audit is problematic for composite destinations and virtual 
topics and when conduit=false b/c the source broker generates the duplicates, 
independent of a producer.
When none of the above features are enabled, a vanilla network, the audit is 
valuable to catch the case where a reply is lost to a successful send.
                
> ProducerBrokerExchange last producer sequenceId initialization needs runtime 
> updates to deal with possible duplicate resends

> Under load, a  buffered pending send can be replayed along with a failover 
> replay (writeTimeFilter initiated) which can miss the audit b/c it won't have 
> knowledge of the original send.
> The dispatch decision is based on the current stored state at the time of 
> reconnect with the expectation that the next message will not be duplicated. 
> It seems under some load and tcp buffering conditions this is possible to get 
> duplicate sends of new messages.
