I encounter an error, when I trying to show messages from my index pattern. After short time, I am receiving error: ``` 70 of 2425 shards failed ``` This message cant be enlarged, I can't click on it so basically, I do not know what is the core issue. I googled little bit and find out, it could be an issue with mapping or with shards. I check it, all my indices are in **green** state. All shards are in **STARTED** state. I implement script, to query every index with: ```auto curl -s 192.168.24.117:9200/$index/_search ``` I received no errors, an I also check the number of documents returned from `/_cat/indices` and `$index/_search`, they are matched. I checked logs but when I perform request I can see no error in ES or Kibana. I have approximately 550 indices, their mappings are created dynamically during index creation. I create assumption that the problem could be with mappings (not sure). Can anybody helped me to find and fix damaged indices? Kibana version: **6.7.1** Elastic version: **6.7.1** ---

After a day of investigation, I found a solution. Because I was not able to find any error in Kibana or Eeasticsearch, I decide to use google chrome **DevTools** -\> **Network tool**. In response data from Kibana, there were **14** indices with **type** and **reason** of error: ``` reason: "Trying to retrieve too many docvalue_fields. Must be less than or equal to: [100] but was [172]. This limit can be set by changing the [index.max_docvalue_fields_search] index level setting." type: "illegal_argument_exception" ``` So I change settings for all indices from response and update **max\_docvalue\_fields\_search** : ``` PUT //_settings { "index.max_docvalue_fields_search" : "100000" } ``` After this change, I am able to use Kibana again without any issue. ---

This is fixed in the future release of 7.11: [https://github.com/elastic/kibana/issues/22897](https://github.com/elastic/kibana/issues/22897) ---
