Lorenz Quack resolved QPID-7958.
--------------------------------
Resolution: Fixed
> [Java Broker] [AMQP0-10] References to messages sent by
> $virtualhostProperties node retained by store
> -----------------------------------------------------------------------------------------------------
>
> Key: QPID-7958
> URL: https://issues.apache.org/jira/browse/QPID-7958
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-broker-7.0.0
> Reporter: Keith Wall
> Priority: Critical
> Fix For: qpid-java-broker-7.0.0
>
>
> On the 0-10 path, I notice that references to messages created by the
> {{${virtualhostProperties\}}} node are being retained internally within the
> store. This is leaking approximately ~1024 bytes per connection. Restarting
> the Broker or recycling the virtualhost frees the memory.
> The reference are being retained by the {{AbstractXXXMessageStore#_messages}}
> set.
> QPID-7783 added the _messages data structure. -It was back ported to 6.0 and
> 6.1, so the leak might be present there too. I have not verified this-.
> (updated 2017/10/06 does not affect 6.1 or 6.0. The
> MessageInstanceConsumerPair, which is no longer on master, unconditionally
> took a reference, so a reference was already taken).
