-----------------------------------
[~gsim], it doesn't look like this patch made it in. Do you remember what happened?

> Key: QPID-5337
> URL: https://issues.apache.org/jira/browse/QPID-5337
> Project: Qpid
> Issue Type: Bug
> Components: Python Client
> Affects Versions: 0.22
> Environment: RHEL 6.4
> Reporter: Renier Morales
> Assignee: Gordon Sim
> Labels: memory-leak, performance
>
> We have found with python-qpid-0.22 that you have to acknowledge all messages received, even if you have subscribed using mode:browse (where ack does not apply) or even if you have subscribed to an unreliable topic exchange (where ack is not needed).
> In these cases, if you don't acknowledge the messages received, memory is leaked, due to the accumulation of messages in an internal unacked list at the client.
> More information at this qpid-users mailing list thread:
