Andrew Stitcher commented on PROTON-1783:
-----------------------------------------
When examining the humg process it seems that there are 3 remaining threads
created by the process (out of 5).
The container runner thread is sitting waiting in the proactor for another event
2 receiver threads are waiting on the condition variable {{can_receive_}}
The 2 sender threads have already exited.
The atomic count {{remaining}} is 9; so 11 messages have been sent and
received, but 9 have either been sent, but not received, or not even sent.

> Key: PROTON-1783
> URL: https://issues.apache.org/jira/browse/PROTON-1783
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.21.0
> Environment: Windows
> Reporter: Andrew Stitcher
> Assignee: Andrew Stitcher
> Priority: Major
>
> There is a sporadic test failure in the Windows CI (Appveyor):
> It happens in the cpp-example-container test. The
> multithreaded_client_flow_control example hangs and doesn't exit.
> This seems to only be an issue on Windows - the Linux/MacOS CI runs don't
> seem to hang in this way.
