It seems to be an internal error in elsticsearch.I'm using 2.3.2 and one shard can not recover from the restart.Cluster yellow all the day.The log says
RemoteTransportException[[10.10.3.16][10.10.3.16:9300][cluster:monitor/nodes/stats[n]]]; nested: AlreadyClosedException[this IndexReader is closed];

Is there some way to make my cluster green again?
