Nodes out of cluster- ES crash- crash logs?


(Divya Malini) #1

Hi,
[ES2.4.1]
We have a 11 node cluster[3master, 3query, 5data]. Two nodes [Master1 and Query1] suddenly left the cluster for around 30 mins .
All I could see in the logs is

Caught exception while handling client http traffic, closing connection...
java.io.IOException: An existing connection was forcibly closed by the remote host

and

connect_timeout[30s]]; nested: ConnectException[Connection timed out: no further information: ];

The ES dashboards indicates that the memory/processortime/heap usage was very normal and there weren't any spikes.

Other than the fact that Master1 and Query1 were re-started on ES crashing, how do i verify why it crashed in the first place ?

Any help or clarification here would be really appreciated. Thanks in advance!
