Subject [jira] Commented: (AMQ-1845) Message loss in network of brokers when network connection break
Date Tue, 22 Jul 2008 12:06:01 GMT

Your code has problem. It works in your case beacuse DefaultMessageListenerContainer by default
creates 1 consumer.  In common, you have to change 

static int i = 1; to static AtomicInteger i = new AtomicInteger(1);
and i++; to i.incrementAndGet();

>          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
> 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.
