   Is there any chance that the controller receives any ping message via Kafka from other than your invokers?
   
   This is a similar case that I faced once.
   If controllers receive a ping message from the `invokerN`, it will populate all statuses for `invoker0 ~ invoker(N-1)` even if there is no message from them. Surely their statuses are offline.
   
   Last time, when I faced this I only had 10 invokers but statuses for invoker10 ~ 14 were also being maintained.
   And I found one debris invoker whose name is invoker14. And it kept sending Ping message to the Kafka.
   
   If you make sure there is no other invoker configured in the host file and you chose the correct target environment, I suspect you may be under the same situation.
