nova-compute does not send Basic.Publish to conductor and service flaps UP/DOWN in `nova service-list` Red Hat OpenStack Platform 13

Issue

nova-compute does not send Basic.Publish to conductor and service flaps UP/DOWN in nova service-list Red Hat OpenStack Platform 13

We can see that the service status normally updates every 10 seconds but between 17:03:00 and 17:04:20, we receive no updates for compute-5:
