Elastic Stack Elasticsearch

Hi all,

We are using ES 1.3.7 cluster with 2GB heap and we are on ES upgradation process.

One Shard got corrupt after OOM occurs in one node.
Before this issue, following message is in log

Why it got corrupt ??? due to OOM or anyother reasonsss???'

please suggest how to overcome this issue (Please don't specify upgrade )..

Upgrade.

Or you will have to live with that kind of error.
You may try to only increase your RAM on your server but corruption can still happen.
