----------------------------------
Summary: 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
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?
