Alex Rudyy updated QPID-7987:
-----------------------------
Attachment: 0002-instrumentation.patch
Attached a patch with some instrumentation code allowing to detect the QBB
leak. An existing test
{{org.apache.qpid.test.unit.transacted.TransactionTimeoutTest#testProducerOpenCommit}}
reproduces the leak
> [Qpid Broker-J][AMQP 0-10] QpidByteBuffer can leak when local transaction
> open/idle time exceeds the maximum open/idle timeout causing session close
> but a new message arrives at the same time when session is in process of close
> -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

>
> {{QpidByteBuffer}} can leak when broker operates with configured open and
> idle transaction close timeouts (
> {{virtualhost.storeTransactionOpenTimeoutClose}} or/and
> {{virtualhost.storeTransactionIdleTimeoutClose}}) and the transaction timeout
> occurs causing the Broker to close the underlying session but at the same
> time a new message arrives. The new message {{QpidByteBuffer}} might not be
> disposed.
