Hello All,

We are using elasticsearch with version 7.6.2 with 9 data nodes and 3 masters.

We are getting an error on scroll requests as defined below;

```
> Elasticsearch exception [type=exception, reason=Trying to create too many scroll contexts. Must be less than or equal to: [1024] on specific shards.

```

When I recreate index it works for a while.First of all, it fails always shard number 4, then reindex it fixed but now it fails on index number 0.

Regards.

Enes.

It sounds like you are using a lot of scroll queries and are hitting system limits. What is the use-case? Can you provide some additional details about you cluster, data and queries?
