      Restart the traffic_manager and traffic_server processes on the local node.
  
      This option modifies the behavior of traffic_line -b and traffic_line -L
      such that traffic_server is not shut down until the number of active client
      connections drops to the number given by the
      proxy.config.restart.active_client_threshold configuration variable.
