Additional information

[sairon]

This looks like a problem in some of the add-ons, as supervisord nor s6-svscan aren't part of the the main HA components. You haven't said which version was installed before 16.1 but you can check if downgrade, or just even a simple reboot, fixes the problem. Otherwise go through the installed add-ons one by one and check their logs/usage or disable them to see which one causes it.

[fysmd]

Reboot does not fix it :(

I'll try to rollback this evening but other than netdata is there any way to find an addon's CPU load?

[fysmd]

I don't run that many add-ons, I think I found the culprit:

Which is particularly annoying as I don't actually use it, just left it there after an experiment with Frigate :( Grrr....

I'll confirm in a while but it seems pretty clear from above!

[fysmd]

Confirmed, Issue was with ADDON Exadel CompreFace.
Disabled and CPU back to expected levels.

I did not revert, sorry for the red-herriing!

Closing.

[sairon]

Right, there's actually bug in CompreFace < 1.2.0 that's emerged with 15.0 release already, see #3960
