in the case of failover with a pending send, so a message send where the reply from the broker is lost, the state tracker with tracking enabled, will resend the message on a reconnect. If the message is already in the store, the producerAudit persisted by the store will detect the duplicate send and ignore it. so, yes it is. See the org.apache.activemq.transport.failover.FailoverTransactionTest for a unit test that simulates this.
