I've also encountered this when writing programs that are SCGI servers that do a fork. SCGI is like FastCGI; the HTTP server passes requests to a local server using a custom protocol. If the fork doesn't close the SCGI server port, then Apache does nothing until the forked subprocess exits, because the subprocess is keeping the request socket open and alive. One fix is to always use subprocess.Popen and specify that close_fd=True, which wasn't difficult for me, but I can imagine that an easy way to set close-on-exec would be simpler in other cases. --amk _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
