----------------------------
> If all consumers of a queue use selectors then the broker will leak memory

> Key: QPID-623
> URL: https://issues.apache.org/jira/browse/QPID-623
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: M2
> Reporter: Martin Ritchie
> Assignee: Martin Ritchie
> Fix For: M2
>
> Attachments: QPID-623-test.patch
>
>
> Because the main _messages queue still has a reference to the msgs incase a
> non selector consumer joins the AMQMessage object cannot be collected by GC.
> There is a log statement saying queue needs cleaning up.
> A simple soution which will not necessarily solve the problem 100% is to
> purge the main queue from the head stopping when a non taken msgs is reached.
> Easy change to make but does allow taken msgs to back up behind. Problem is
> to process/purge those msgs will be harder as more locking will be required.
> This is somthing the reaper thread can do when implemented for full TTL
> (QPID-499).
