Steve Huston commented on QPID-1952: ------------------------------------ The patch adds a call to queueForDeletion, but close() already calls that. I think there may be an issue with a queued delete not taking effect later. I'll check into that a bit. If you have any insight into this area from your debugging, that would be helpful too. Thanks. > C++: client request memory leak on windows > ------------------------------------------ > > Key: QPID-1952 > URL: https://issues.apache.org/jira/browse/QPID-1952 > Project: Qpid > Issue Type: Bug > Components: C++ Client > Affects Versions: 0.5 > Environment: Windows XP Pro w/SP3 > Reporter: David Rennalls > Attachments: Connector_memory_leak.patch, Main2.cpp > > > I'm experiencing a memory leak when using the client library on Windows (0.5 > release) when sending a single request.

However in > AsynchIO::queueForDeletion() aio.opsInProgress > 0 so the 'delete this' > branch is not done. There are no more queueForDeletion() calls made on the > aio object (after opsInProgress is 0) and so it never gets deleted.
