Hi Ben, I’ve set [oslo_messaging_rabbit] heartbeat_in_pthread = True and of course restarted the control plane, but it seems nothing has changed - still have disconnections in logs > Wiadomość napisana przez Ben Nemec <openstack at nemebean.com> w dniu 17.09.2021, o godz. 18:57: > > This sounds like you're hitting the heartbeat/eventlet bug. Basically eventlet won't schedule the heartbeat thread unless something is regularly waking up the api threads.
