      When master nodes or kube api servers are taken offline, for mc update, revision rollout, etc .. a single kube api server will contain the majority of long lived connection and live connections.
      After all 3 masters are back online a single kube-apiserver will continue to receive the majority of live api connections resulting in the master node cpu hitting 100%

      Restarting the kube api server pod resolves the issue.

      The expectation is that after the 3 masters are up the live api connections would get balanced between the 3 master nodes.

      Looking for assistance in determining why the live connections are not getting evenly distributed between the kube api servers whenever quorum is reestablished.
