High CPU Usage After new Installation of openHABian Bookworm

Hello everyone,

I recently upgraded my system from Debian Bullseye to Bookworm. Since the upgrade, I’ve noticed frequent occurrences of high CPU load.

I should mention that I never monitored the CPU usage through “top” on Bullseye since I didn’t experience any issues back then.

I would appreciate any input on whether others have observed similar behavior after the upgrade, and what steps I could take to identify the root cause.

Thanks in advance!

Especially for openHABian, we do not recommend to do an upgrade but a complete new innstall with backup and resrore of your openHAB config.
We had a lot information in the past, where OS upgrades failed completely.

Here I am again being unclear, sorry! :man_facepalming:t3:
That is exactly what I did. :slight_smile:

I did reboot the RPi and for several hours it was like this:

Now we’re back to CPU usage < 200%
I will restart again but rebooting the system two times a day cannot be the solution. :frowning_face:
