After upgrading from 7.14.2 to 7.15, some existing metric visualizations that use percentiles have stopped working.

```

steps to reproduce:

- Visualize Library \> new visualization \> aggregation based \> metric
- choose an index source (that has a lot of documents)
- add metric
- aggregation: percentiles
- field: any number field
- time window that result in \> 150k documents
- update

Hi @jsteenkamp ,

I've tried to reproduce with the sample data but could not.  
Can you provide some more information about the index pattern size? Do you have a particular high number of fields, or high number of documents (\> 20k documents)?

Hi @Marco_Liberati, thank you for your feedback. I can confirm that it only happens at some of the indices we are using. I have already updated the description to:

> After upgrading from 7.14.2 to 7.15, **some** existing metric visualizations that use percentiles have stopped working.

If I take a small time window, for instance 5 minutes, it works. If I change the time window to 1 hour, it fails. Looks like this issue is related to the number of documents. This particular index fails above 155k documents.

Hi @jsteenkamp ,

the bug has been confirmed and a fix is on the way: [Error in visualizations with percentiles for indices with many documents · Issue #113215 · elastic/kibana · GitHub](https://github.com/elastic/kibana/issues/113215)
