Log shows - 2018-12-26 00:00:35.774 7 INFO oslo_service.service [-] Caught SIGHUP, stopping children 2018-12-26 00:00:36.077 40997 ERROR oslo_service.service [-] Error starting thread.: RuntimeError: A fixed interval looping call can only run one function at a time openstack commands that needs neutron fails ( e.g openstack server list ) Restarting the docker ( neutron_api ) resolves the problem. Steps to reproduce ================== Deploy. Wait 4 days. Expected result =============== Service should remain healthy.. Actual result ============= not healthy .. Environment =========== Rocky , container based. Logs & Configs ============== Logs : http://paste.openstack.org/show/738658/ More info: ========== Google showed this - https://bugs.launchpad.net/oslo.service/+bug/1547029 follow by - http://paste.openstack.org/show/487420/ It seems that if we'll add "eventlet.sleep(0)" in <<<HERE>>> below, it might resolve the issue. - def run_service(service, done): """Service start wrapper. :param service: service to run :param done: event to wait on until a shutdown is triggered :returns: None """ try: <<<<< HERE >>>>>>>> service.start() except Exception: LOG.exception('Error starting thread.') raise SystemExit(1) else: done.wait() The problem is that I didnt come up with an easy way to reproduce the issue in order to confirm it.
