Scroll failed on some shards?

Elastic Stack Elasticsearch
1

Hi,

We're using 6.2.3, and I noticed some errors in our application logs yesterday that indicated a few shards (eg, 1-4 out of total of 90) failed while processing a scroll request. Unfortunately I don't have access to the Elasticsearch logs, only the application logs, and they just show number of failed shards from the _shards.failed field in the response, but no reason.

Since they're scrolls, I thought it may be a timeout, but to affect only a few shards seems odd.

What situations could cause this to happen?

6.X is EOL and you really need to upgrade ASAP.

It'd be useful if you shared the complete error that you are getting.
