Subject [jira] Created: (AMQ-1845) Message loss in network of brokers when network connection break
Date Tue, 08 Jul 2008 13:35:01 GMT
Message loss in network of brokers when network connection break

                 Key: AMQ-1845
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.1.0
         Environment: Two brokers connected via TCP with one persistent distributed queue
and a producer and a consumer on each broker.
            Reporter: Bryan Shaw

Producer on broker A send 2500 message on the distributed queue at broker A.
Producer B starts to receive message from distributed queue on broker B.
During the receiving process, the network between these two brokers down and later brought
up again.

In this senario, we found that some messages are lost. 
It seems the broker A are sending message to broker B when the network is down and these messages
are removed from queue in broker A but never received by broker B which causing message loss.

Is this a bug or a configuration problem? 
I thought the configuration like this is the store/forward pattern which should ensure the
message reliability in an unstable network.
