Giovanni Toffetti commented on AMQ-1509:
----------------------------------------
Thank you Howard.
I'm afraid the temporary fix you propose wouldn't be of much use in my case. I
am currently working at comparing how well our in-house distributed pub/sub
solution routes packets with respect to ActiveMQ on a generic network of
brokers: if I implement the temporary fix ActiveMQ performance wouldn't
probably be as good as it should invalidating my test. I guess I'll have to
find another MOM for the experiments while ActiveMQ gets fixed. Did any of you
ever use any other JMS implementation supporting generic (cyclic) networks of
brokers?
Using pub/sub on networks of brokers must not be so common after all, I would
have expected this bug to receive much more comments.
Thank you again.

> 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/[EMAIL PROTECTED]/msg05198.html.
