My hot node is already outputting this log. What is the problem?

```auto
{"type": "server", "timestamp": "2021-12-17T19:45:21,865Z", "level": "WARN", "component": "o.e.h.AbstractHttpServerTransport", "cluster.name": "dev", "node.name": "dev-es-data-node-hot-0", "message": "caught exception while handling client http traffic, closing connection Netty4HttpChannel{localAddress=/192.168.137.234:9200, remoteAddress=/192.168.189.0:56454}", "cluster.uuid": "QLe8A3BCQDCakdsf1MplIA", "node.id": "6b1q03rCQEqEce5FOvVN4g" , 

```

This could be anything causing this issue. Also, it's a warning, not an error, so it's likely something that can be ignored. Additionally, this appears to be an Elasticsearch issue, not specific to ECK. You likely would get a more timely, and pointed response [Here](https://discuss.elastic.co/c/elastic-stack/elasticsearch/6)
