Subject [jira] [Commented] (AMQ-3891) Durable subscribers receiving duplicate messages
Date Fri, 27 Jul 2012 08:21:35 GMT

    [ https://issues.apache.org/jira/browse/AMQ-3891?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13423738#comment-13423738

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

The test app it self will not show an issue, you will only be able to see the issue in the
admin web interface, where you can see messages beeing dispatched multible times.

Besides that this seems to be related to some of the other issues raised, so if the topic
that the durable subscriber subcribs to is not configure in the config file the problem goes
away.

It also do seem like the issue has been resolved in the 5.7 version, is there any info on
when this version is in a stable release?

Thanks for your help, I belive that this issue can be closed now.

> 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...
