STINNER Victor added the comment: The problem is that socketserver.ForkinMixin doesn't wait until all children completes. It's only calls os.waitpid() in non-blocking module (using os.WNOHANG) after each loop iteration. If a child process completes after the last call to ForkingMixIn.collect_children(), the server leaks zombie processes.
The server must wait until all children completes. Attached PR implements that. The bug was be reproduced with the attached forkingmixin_sleep.patch. haypo@selma$ ./python -m test -v -u all test_socketserver --fail-env-changed -m '*Fork*' (...)
