Arthur Naseef commented on AMQ-5107:
------------------------------------

Thanks Gary - I'll take a look at that; if it proves to be straight-forward and effective,
I'll put it in there.

>                 Key: AMQ-5107
>                 URL: https://issues.apache.org/jira/browse/AMQ-5107
>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Transport
>    Affects Versions: 5.9.0
>         Environment: Windows 7 64Bit - Java "1.6.0_20"
> CentOS 6.0 - Java "1.7.0_09-icedtea" 
>            Reporter: Greg Garlak
>            Assignee: Arthur Naseef
>             Fix For: NEEDS_REVIEW
>
>
> To reproduce: 
> 1) Start 3 or more listener processes (see listener code below)
> 2) Run producer to push one message on queue (see producer code below)
> 3) One of the listeners will pick-up the message and sleep for one minute before auto
acknowledging the message
> 4) Start a shutdown sequence of the broker within the 60 second window (Ctrl-C or issue
Terminate jvm(int) command from Hawtio console) 
> 5) All other idle listeners should get the same message redelivered simultaneously, each
one having deliveryCount incremented
