             Summary: [Java Broker] [AMQ0-10] 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
            Reporter: Keith Wall


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.

From a brief look, on ConsumerTarget_0_8, it is the NoAckConsumer taking/releasing of the message reference that causes the store to forget the message.  It looks like org/apache/qpid/server/protocol/v0_10/ConsumerTarget_0_10.java:331 (the else path) should have something equivalent.

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.
