Message211839
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."
