> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.2.0
> Environment: solaris 10
> Reporter: ying
> Assignee: Dejan Bosanac
> Fix For: 5.4.0

> 1. producer of VirtualTopic.testTopic publish message to brokerA
> 2. consumer 1 on brokerB with "Consumer.A.VirtualTopic.testTopic
> consumer 2 on brokerB with "Consumer.A2.VirtualTopic.testTopic
> 3. brokerA and brokerB are bridged.
> Result: you will get
> ERROR MasterBroker - Slave Failed
> javax.jms.JMSException: Slave broker out of sync with master - Message: ID:yhe-1337-1236273055924-0:16:1:1:738 on queue does not exist among pending(0) for subscription: ID:yhe-3603-1236271682179-0:13:1:1
> Reason:
> In TransactionBroker.java there is a ActiveMQMessageAudit and it will be configured if the broker is a slave. ActiveMQMessageAudit is using the messageId alone to check whether the message is a duplicate. The message for consumer2 will be ignored as duplicate and not saved to the message store because consumer1's same message arrives early.
