David Rennalls updated QPID-1952:
---------------------------------

    Attachment: Connector_memory_leak.patch

This fixed the leak for me. I'm only using the client library and don't know if 
this leak exists in the broker's usage.

> I'm experiencing a memory leak when using the client library on Windows (0.5 
> release) when sending a single request. From what debugging I've done so far 
> it looks like the The AsynchIO object used by the TCPConnector is not being 
> deleted.  When the connection is being closed aio->queueForDeletion() is 
> called from TCPConnector::closeInternal().. 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. The 
> ConnectionImpl object involved is not cleaned up either, the shared_ptr to it 
> has a non-zero ref count but I'm guessing it's related to the AsynchIO object 
> not being cleaned up.
> There used to be some code in AsynchIO::completion() that seems like it would 
> do the necessary delete (see below). It was removed with code changes in 
> https://issues.apache.org/jira/browse/QPID-1550 because 'It fixed a memory 
> corruption on the broker side by deleting too early' (from Steve H.)
> -    // Lock released; ok to delete if all is done.
> -    if (opsInProgress == 0 && queuedDelete)
> -        delete this;
