High CPU Usage After new Installation of openHABian Bookworm

[Neolinger (Antonio)]

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!
That is exactly what I did.

Upgrading OpenHABian: Bullseye to Bookworm with OpenHAB Milestone -> Stable Branch Change

Hi, If this post actually belongs in the “Installation” category, I apologize and ask that it be moved. I’m planning to upgrade my OpenHABian from Bullseye to Bookworm using a fresh install (as dist-upgrade is not recommended). Additionally, I want to switch from OpenHAB Milestone(which I switched to in order to be able to use a device) to the stable branch during this process.

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.
