Shuo Li added the comment: The error message is just a "Port already used".
Possible cause 1: find_port default interface is HOST, which is 127.0.0.1. And in most test cases, they use 0.0.0.0. So they are on different interface. 2: system reuse the port, since I build python on a busy server, that is possible. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29767> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
