Because of socket ownership changes, on reload uwsgi is no longer possible to chown its socket, and dies on `service uwsgi reload' In log: chown(): Operation not permitted [core/utils.c line 2623] In source: if (chown(filename, new_uid, new_gid)) { uwsgi_error("chown()"); exit(1); } Probably an upstream problem, I've filed bug there as well: https://github.com/unbit/uwsgi/issues/1471
