      Description

      "Yes, I have. Unfortunately, I never quite around to fixing it. My guess is
      that it is caused due to a race condition between the rebalance thread and
      the offset commit thread when a rebalance is triggered or the client is
      being shutdown. Do you mind filing a bug ?"
