> We have seen a few cases where an unexpected error in the Raft IO thread causes the process to enter a zombie state where it is no longer participating in the raft quorum. In this state, a controller can no longer become leader or help in elections, and brokers can no longer update metadata. It may be better to stop the process in this case since there is no way to recover.
