All of a sudden, our cluster has started to receive a huge of amount of "es\_rejected\_execution\_exception" errors when upserting. Nothing has really changed on our code side so we are at a complete loss. Our main API is now now serving stale data as a result.

This is of a major priority. Any help would be greatly appreciated.
