Raspbery pi 3 with Kodi 18.7 crashing every few days

Hello

My raspberry pi 3 with kodi 18.7 is crashing every few days:
Crashing explained:
Screensaver: date & time from a few days ago
no reaction on mouse or remote from TV.

connected via putty: sudo reboot not working
systemctl stop mediacenter
systemctl start mediacenter
both not working

only thing that working is pulling out the power adapter en replugging it in.

here are my logs: https://paste.osmc.tv/busitoyifu

any of you an idea where to look to solve this problem?

Regards

Sven

Try it with these three lines removed from your config.txt

arm_freq=900  
core_freq=450  
sdram_freq=450

Do you have any idea where these values are coming from?
I never set up these values.

Regards

Sven

There was a bug in the My OSMC add-on some time back which caused the file to be modified when you entered the overclocking section even when you did not set any values or tell it to save. This function has since been removed from the add-on so if you edit those out it will not happen again.
