While doing bulk request to bulk API I got response with errors:

```auto
Type: (string) (len=23) "illegal_state_exception",
Reason: (string) (len=30) "Too many cached tokens (> 100)"

```

I tried to Google this `Too many cached tokens (> 100)` error, but found nothing.  
Please help me to understand the problem.

ES version: 7.4.1

What do your Elasticsearch logs show?  
What is the full error from Elasticsearch?
