And it goes on. After this I normally reboot the Pi and it works again for a few hours.
If I check the events.log I can see that it stoped being populated a few minutes prior to the error.
I don’t know where to start looking, if it’s related to some Addon, or a core issue.
Any help would be appreciated.
