Gordon Sim reassigned PROTON-1120: ---------------------------------- 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? > {code} > ============================================ > 10000 messages > ============================================ > total kB 242088 16256 7552 - sending > total kB 293980 68224 59520 - sent > total kB 293980 68228 59524 - receiving > total kB 294236 68340 59632 - received > Size Growth Context > __________|____________|__________ > 242088 kB +242088 kB sending > 293980 kB + 51892 kB sent > 293980 kB + 0 kB receiving > 294236 kB + 256 kB received > ============================================ > 20000 messages > ============================================ > total kB 294236 68348 59640 - sending > total kB 397820 171896 163232 - sent > total kB 397820 171900 163236 - receiving > total kB 398020 172060 163396 - received > Size Growth Context > __________|____________|__________ > 294236 kB +294236 kB sending > 397820 kB +103584 kB sent > 397820 kB + 0 kB receiving > 398020 kB + 200 kB received > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
