Hello, I have a 4 server Elasticsearch server cluster supporting graylog, and all of a sudden things have stopped working. Elasticsearch logs do not show any overt issues. The cluster is green, etc. However, graylog has millions of messages piling up unprocessed and the search features are not working. I am not out of diskspace on any of the servers on the cluster. ---

What is the full output of the [cluster stats API](https://www.elastic.co/guide/en/elasticsearch/reference/7.10/cluster-stats.html)? ---
