False positives from ConnectionAudit duplicateChecker when there are gaps in
the message sequences received by a consumer
-------------------------------------------------------------------------------------------------------------------------
Key: AMQ-1742
URL: https://issues.apache.org/activemq/browse/AMQ-1742
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.1.0
Environment: all
Reporter: Gary Tully
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.
