> a consumer can miss messages with failover transport as the connection audit suppress duplicates feature is enabled for failover connections.
> When there are gaps in the message sequence that span the audit window or when message ids are multiples of 64 the BitArrayBin that backs the AuditChecker gets out of sync and can report false positives, rejecting a duplicate message in error.
> If it is suspected, enable log4j.logger.org.apache.activemq.ActiveMQMessageConsumer=TRACE to see an event when a duplicate is recieved.
