Hi I'm using a single-node elasticsearch server. I have 400+ indices with 100GB+ data in cluster and shard count of each index is 5. When i'm trying to check the data for an index in discover page in kibana. I got the below error. whereas dashboards are working fine without any issue. 1 of 5 shards are failed. max\_bytes\_length\_exceeded\_exception bytes can be at most 32766 in length; got 46350 Error: Internal Server Error ELK version - 7.10.0 Could someone please assist, what can be done for this issue. Thanks ---

Many things are wrong here IMO: - 7.10 is totally outdated. At least go to 7.17 or better 8.10.3. - 5 shards per index. Why? - 2000 shards on a single node. You did not tell how much HEAP you defined > max\_bytes\_length\_exceeded\_exception bytes can be at most 32766 in length; got 46350 Might be because you are getting back a lot of content? Like running a query on logs indices with size=10000? May I suggest you look at the following resource about sizing: > **[Size your shards | Elasticsearch Guide \[8.11\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/size-your-shards.html)** ---

typo correction. ES has 100+ indices and shards are 500+. I need to use ES 7.10.0 only. ---
