## Problem/Question

Netdata consuming high CPU after OS upgrade (\>90%)

- clearing /var/cache/netdata/\* did not help.
- systemctl stop netdata, and running the docker instance of netdata had the same performance hit.

I can’t use netdata in my production at this time as it is causing performance issues.

Hi, @Sean_Kennedy. Can you check which process/thread is consuming CPU resources? See how to [do it using htop](https://github.com/netdata/netdata/issues/14892#issuecomment-1505296000) (search for the netdata parent process and scroll down until you see the thread with 100%).

This is in a proxmox environment - with 4 vcpus, min ram 512MB, 4GB allocated. These are light weight VMs running python containers.

Here’s what it looks like when systemctl stop netdata

Netdata doesn’t use a lot of CPU on your htop screenshots.
