      we find an api service sometimes get timeout return after we update it yesterday. 

      everything about this api service looks like ok on marathon page. then we login the server which the service instance is running and check its ipvs table.

      TCP wlc                                                                                                                                      
        ->                 Masq    1      0          0         
        ->                 Masq    1      0          0
     is the current container address which is running. but is the container address which has been killed when marathon update the api service.

      so when virtual server access its always timeout.


      we try to delete by ipvsadm but after a while the dead server comeback again. maybe navstar has persistent storage with ipvs table and always sync from each other in cluster.


      so why the killed real server information won't be cleanup in cluster?
