Hi,

I'm running ELK Stack 7.10.0 (elasticsearch, filebeat, kibana, logstash) on the same server. And since two days elasticsearch is doing something every 6 minutes for one minute. The CPU usage is not high, but it's little annoying. I can't see what is happening in the elasticsearch logs.

I'm running it on Ubuntu 20.04.1with

```
openjdk version "11.0.9.1" 2020-11-04
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.9.1+1)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.9.1+1, mixed mode)

```

Someone any idea? The server is in idle mode. No load from other processes.

Regards,  
Rafal

The [nodes hot threads API](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-hot-threads.html) will tell you the details of what every node is busy doing. If you need help interpreting its output, feel free to share it here or in a [gist](https://gist.github.com/).

I fixed the problem. After the upgrade to 7.10.0 I removed two days ago the filebeat-7.9.3 template. But there was an empty filebeat-7.9.3-2020-xx-xx-xxxx index. After I removed it (after my post here) the CPU usage is gone.

I don't understand what was the problem, but now it's look good.
