Giovanni Toffetti commented on AMQ-1509:
----------------------------------------

Hi all,

I'm also wondering how to get to the patch for this issue, it seems it's not included in the
RC4 release of 5.1.0.
Did anybody manage to solve the problem?

Thank you.

> 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.
