 Is it an error or a normal behaviour of neutron agents ?

Agents report their own status to neutron-server periodically. The default inter time is 75 seconds. If neutron server can't recieve the report in 75 secods,the alive of the agent will be xxx. And it will be changed to :-) after recieving new status report.

Translates into : If this happens all of the time and is causing issues with scheduling then you should look into load on the servers where the agents are running, look into the logs of the agents, see if there are any issues with scheduled tasks.
