----------------------------------
Assignee: Gordon Sim
> Memory leak using proton.utils
> ------------------------------
>
> Key: PROTON-1120
> URL: https://issues.apache.org/jira/browse/PROTON-1120
> Project: Qpid Proton
> Issue Type: Bug
> Components: python-binding
> Affects Versions: 0.10
> Environment: python-qpid-proton-0.10-2.fc23.x86_64
> And 0.9-13
> Reporter: Jeff Ortel
> Assignee: Gordon Sim
> Attachments: memory-leak.py

> I have observed a fairly substantial memory leak using the blocking classes in proton.utils. Mainly with sending messages.
> Observations:
> {code}
> growth = 52 MB for 10,000 messages sent
> growth = 104 MB for 20,000 messages sent
> leak = 52 MB per 10,000 sends or ~5 kB / send
> {code}
> The attached reproducer, can be used to collect and display statistics. There is likely a better method for measuring the memory growth but this was easy. Perhaps there is something incorrect/missing with the way I'm using proton or measuring the memory growth/leak?
