Leo Riguspi commented on QPID-6935:
-----------------------------------
Hi Rob,
the content in each transfer object seems to be different, at least for the
ones we looked at. But there were 49000 Transfer objects in the previous heap
dump and 115000 in the new one so it is not possible to say.
The problem is that we can't even reproduce the error. We tried to inject
several messages, even larger than 10MB. We took heap dumps after each message
but can't see anything abnormal.
Could the issue be in Camel's code?

> 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,

> 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.
