How long does it last?

If it doesn't stop, you should enable request logging in your webserver and examine where the requests come from. There must be either a monitoring script, search engine crawler or a malicious bot making requests to your site.

You can also temporarily blacklist all IPs and see if CPU drops back to zero.

In your PHP flarum output we see debug mode is enabled. When you are done with the investigation, don't forget to turn it off again. The forum will consume a lot more resources when in debug mode.

Something else I notice, if the process takes 400% CPU it must mean you have some special PHP server capable of multi-threading. What kind of webserver/php-server is this? A regular Apache or PHP-FPM should only consume 100% CPU per process.

Thanks for the reply
Frankly, I was surprised by this high percentage
I use a VPS server from Contabo with the following specifications:
4 vCPU Cores
6 GB RAM
100 GB NVMe
And I use the latest Ubuntu operating system
And the cyberpaanel open litespeed control panel

Does the high CPU usage also exist without debug on?
How much traffic does your community get?

Discuss ran on a 512mb droplet at digital ocean with 1 vcpu for years. We only upgraded it due to increased ddosses which Cloudflare didn't consider one (a bit too small).
