> When zxid rolls over the ensemble is unable to recover without manually restarting the cluster. The leader enters shutdown() state when zxid rolls over, but the remaining four nodes in the ensemble are not able to re-elect a new leader. This state has persisted for at least 15 minutes before an operator manually restarted the cluster and the ensemble recovered.
