we had already one week ago a short conversation at the kodinerds forum.
I have noticed at my RPi during webgrabplus is synchronizing the EPG data that one CPU does run with 100%. As soon the task is after one hour complete or I do deactivate the Addon it does disappear.
I did meanwhile check the kodi debug log but there is nothing relevant. I did now attach the complete WebGrab++.log.txt and hopefully you are able to detect more than I.
Beside the CPU utilization everything is working well. Perhaps you have an idea how to improve my settings.
Thanks in advance!
