--------------------------------------------
Summary: Qpid broker memory increases when a receiver is paused
with message pending acks
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
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
