New submission from STINNER Victor: It looks like the overlapped AcceptEx() operation was cancelled by something. But when the test_asyncio was replayed in verbose mode, the test passed.
Is it possible that a local firewall or antivirus cancelled the operation? It would be surprising since the test passed at the second try. Related discussion on Apache HTTPD mailing list: " My guess... you have a package that installed a network service provider filter and that filter is somehow doing a close on the event handle in the overlapped structure." http://marc.info/?l=apache-httpd-dev&m=105959505627302&w=2 --- AcceptEx() documentation: http://msdn.microsoft.com/en-us/library/windows/desktop/ms737524%28v=vs.85%29.aspx test_create_server (test.test_asyncio.test_events.ProactorEventLoopTests) ...
