Vadim Katz updated AMQ-1934:
----------------------------


Could someone please comment on this? It seems very serious because we can't 
rely on AcriveMQ failover.

> Message delivery blocks after broker failover

>                 URL: https://issues.apache.org/activemq/browse/AMQ-1934
>             Project: ActiveMQ
>          Issue Type: Bug
>    Affects Versions: 5.1.0
>         Environment: Windows XP, ActiveMQ 5.1.0, Spring 2.5
>            Reporter: Vadim Katz
>         Attachments: activemq-failover-test.zip

>
> Start two brokers with shared FS. One is locked out because journal is locked 
> by the master as it should be. Then run attached junit test case. The test 
> does the following:
> 1. Sends and receives a message while both master and slave brokers are up.
> 2. Requests manual shutdown of master broker and expects slave to become 
> master within 30 sec
> 3. Sends another message which is never received
> You can observe via admin console that the message sent after broker failover 
> is delivered to the queue; however it is not delivered to a waiting listener. 
> Also, you can observe the logged invocations of TranportListener. Notice, how 
> onCommand() calls are no longer continuously made after failover (except for 
> the first two).
> Eclipse/Maven based test project is attached.
> Please see "sends/receives block during failover" discussion for more 
> information. thanks,
> vadim
