[jira] Commented: (AMQ-1509) Duplicate topic messages received with
network of brokers and selectors
[ https://issues.apache.org/activemq/browse/AMQ-1509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=41012#action_41012 ]
Howard Orner commented on AMQ-1509:
-----------------------------------
I do not see any subversion commits listed nor do I see code changes in files I would have expected to change on the main subversion trunk. Is there a way to get the code changes associated with this resolution? Thanks!

> Key: AMQ-1509
> URL: https://issues.apache.org/activemq/browse/AMQ-1509
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, Transport
> Affects Versions: 4.1.1
> Reporter: Howard Orner
> Assignee: Rob Davies
> Fix For: 5.1.0

> If you create a network of two brokers, A and B, one publisher publishing to A, and n (where n is > 1) receivers with selectors, each receiver recieves n messages for every 1 message sent. The key here is to have a selector. It would appear that the conduitSubscriptions flag does not work when using selectors. The conduit does not properly reconcile consumers if they have selectors. A suggested soltuion would be that ather than process each selector independantly, each selector should be or'ed together and if any selector results in true then a single message should be sent to the other broker.
> In doing research, it would appear that this problem was introduced with bug fix AMQ-810. Another user reported it via email back to the assignee of AMQ-810 and a short dialog transpired. See http://www.mail-archive.com/activemq-users@geronimo.apache.org/msg05198.html.
