Today,one of my data node's cpu usage suddenly rise to 100%(I have 10 datanodes,ony one node's cpu rise).At that time,all api has no response and no timeout (bulk api,stats api and so on).But i can `ping` the datanode.

For example,the api `curl 'localhost:9200/_cat/thread_pool?v&h=id,host,bulk.size,bulk.active,bulk.rejected,bulk.completed,bulk.queueSize,bulk.queue'`. has no response.

Here are master node's log:

```
NodeDisconnectedException[[es165-4][ip:port][cluster:monitor/nodes/info[n]] disconnected
NodeDisconnectedException[[es165-4][ip:port][cluster:monitor/nodes/info[n]] disconnected
NodeDisconnectedException[[es165-4][ip:port][cluster:monitor/nodes/info[n]] disconnected

```

The died state continue to i shutdown the datanode host.

es version:`V2.3.3`
