Elasticsearch stop suddenly

Elastic Stack Elasticsearch
1

Hi guys,

Our cluster has 7 data nodes. Sometimes one of them was turned off (Elasticsearch service sudden stopped). how can I solve the issue.?
And How can I minimize the number of shards because I noticed that the number is very high and that can be the cause of the problem ?

many thanks!!!!

You probably have something in elasticsearch logs or system logs telling you what is happening.
