Hi all,

One of my Kibana instances crashes everytime with below message:

```auto
{"statusCode":401,"error":"Unauthorized","message":"[circuit_breaking_exception] [parent] Data too large, data for [<http_request>] would be [1044243464/995.8mb], which is larger than the limit of [1020054732/972.7mb], real usage: [1044243464/995.8mb], new bytes reserved: [0/0b], usages [request=137887744/131.5mb, fielddata=59490142/56.7mb, in_flight_requests=0/0b, accounting=20335312/19.3mb], with { bytes_wanted=1044243464 & bytes_limit=1020054732 & durability=\"TRANSIENT\" }"}

```

I think that its some memory issue.  
How to resolve it? Any ideas?

Regards

This means Elasticsearch runs out of memory to serve the request. A likely cause is that your cluster is undersized.

it is probably necessary to increase (if possible) the heap memory
