We're operating an Elastic Stack on kubernetes on a single host(Centos 7). The host has 2x Intel E5-2640 v4 @ 2.40GHz. The processes are supposedly working with all cores but the load is mainly on the first cpu. Most of the time cpu load is similar to the image below:

 ![Solar-PuTTY_v1VUvmbJQu](https://us1.discourse-cdn.com/elastic/original/3X/9/c/9c0861e24fdb752cdbb8889d6a095325fb7f7b4a.png)

No restrictions have been configured on the machine or the stack the thread/cpu configs are on default.

```auto
GET _nodes/stats/process?filter_path=**.max_file_descriptors output is "1048576".

GET /_nodes/stats?filter_path=nodes.*.thread_pool.write.threads output is "1"

```

I also see some values under "rejected" from the output of:

```auto
GET _cat/thread_pool?v

```

What might be the cause of this? Something wrong with second cpu? Something wrong with environment options on the cluster? The odd thing is thread count is shown as "1". I have a elasticstack machine as well didnt configure any cpu/thread options the machine has 4cores/8threads and when i check for thread count on elasticsearch it is shown as 8.
