KALYANARAMAN SIVARAMAN commented on QPID-8462:
----------------------------------------------
Also your comment on configuring the hearbeat doesn't work as the server will
just log the even and does not take any action.
"If heartbeating is activated, and a broker does not receive a heartbeat from
the server for delay * (server)timeoutFactor seconds then it logs this event
but does not take any further action (i.e. the connection is not closed, and
processing of incoming data/sending outgoing data still occurs."

> Key: QPID-8462
> URL: https://issues.apache.org/jira/browse/QPID-8462
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Affects Versions: qpid-cpp-1.39.0
> Environment: Linux
>
> Reporter: KALYANARAMAN SIVARAMAN
> Priority: Major
> Attachments: brokerMemoryIncrease.tar
>
>
> Given the situation where we have a receiver "Receiver1" acquire 1 message
> from a queue "ReceiverQueue" but if the message is not acknowledged and
> Receiver1 process is paused using kill -STOP <pidOfReceiver1>.
> Any further messages sent to ReceiverQueue is marked as DELETED even though
> we have another receiver "Receiver2" properly acquire messages from the queue
> and also sends acknowledgements, the broker memory linearly increases until
> all the memory in the box is used. Purger cleaning up messages does not help.
> Once we kill Receiver1 the broker memory stabilizes.
> All of the repro steps are automated in the attached reproducer.
>
> Please follow the steps to reproduce the issue
>
> Step 1: tar -xf brokerMemoryIncrease.tar
> Step 2: cd brokerMemoryIncrease
> Step 3: ./qpidRepro.sh
