[jira] [Commented] (AMQ-3891) Durable subscribers receiving duplicate messages

    [ https://issues.apache.org/jira/browse/AMQ-3891?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13407896#comment-13407896 ] 

Emil Kongelys commented on AMQ-3891:
------------------------------------

Are you able to reproduce the issue, or do you need more information? I'm using NMS/C# and not java.

We have attached wireshark to confirm that the messages was sent from the AMQ broker, and it was not a problem in NMS.

>            Reporter: Emil Kongelys
>            Priority: Critical

> This is what it seems to take to reproduce this:
> •         The durable subscriber is connected to the message broker, using the failover protocol
> •         The message broker is then restarted (with the client running)
> •         The client application is then restarted
> o   The client now receives two copies of every message!
> •         Try restarting the client again
> o   The client now receives three copies of every message!
> •         And so on...
