Rob Godfrey closed QPID-6935.
-----------------------------
Resolution: Cannot Reproduce
> Infinite recursion resulting in huge number of Transfer objects created in
> Delivery, until OutOfMemory
> ------------------------------------------------------------------------------------------------------
>
> Key: QPID-6935
> URL: https://issues.apache.org/jira/browse/QPID-6935
> Project: Qpid
> Issue Type: Bug
> Components: JMS AMQP 1.0 Client
> Affects Versions: 0.32
> Environment: Linux RedHat 7
> Reporter: Leo Riguspi
> Priority: Blocker
> Attachments: Heap.png, Heap2.png, memory_dump.txt, snapshot1.png,
> snapshot2.png
>
>
> We have an Apache ActiveMQ 5.12 running for 2 months now and a Java AMQP
> client publishing a few messages every few minutes. Messages are small, less
> than 1K and are immediately consumed.
> For the second time in two months the client exploded with an OutOfMemory
> error. By analysing the memory the culprit seems to be the ArrayList of
> Trasfer objects in the Delivery. All of a sudden, for some reason it just
> keeps creating new Trasfers until the memory is full.
> We have a screenshot of the memory dump in which there are more than 49000
> Trasfer objects in the same Delivery. Unfortunately there seems to be no way
> to attach it to this issue.
> We did not find a way to reproduce the problem but it looks like some
> combination of conditions cause the SessionEndpoint::sendTransfer recursive
> method to call itself over and over, each time adding a new Transfer object.
