The title says it all, and I also asked the same question here: https://stackoverflow.com/questions/67464225/digitalocean-server-cpu-100-without-app-running

Not sure which is the right place to ask this question.

Here's the full page screenshot of the htop results: enter image description here

What can I do to start investigating the cause?

Atm, there's no app running or anything when I ran the htop, but I have tested running an app and it runs without issues close to 24h till it stops running and server stops responding.

Any help is highly appreciated!

  • Ubuntu 20? There is no such release. Ubuntu uses yy.mm format (year.month of release) for all server & desktop releases, the yy being used only for IoT and specialist appliance/devices and cloud use that can use snap packages only. Please clarify which product you are using (year only releases mean a different product since 2016) By Ubuntu 20, do you mean Ubuntu Core 20?

  • Sorry, a bit misleading I guess. My vps (digitalocean) OS is Ubuntu 20.04

  • Oh my F god, I ran pm2 save --force to sync running processes and the CPU went back to normal. I guess there was an app stuck or something that ate all the CPU. The one-click installation had an example app running I guess. Damn, that was unexpected.

  • Please correct your question then, Ubuntu 20 does imply it's the snap only product Ubuntu Core 20 (and not deb based which use year.month format in releases).
