That's weird, I've never saw this error on here.
What I see, accessing cpanel, was lots of this error:
File not found [/home/dbfinter/public_html/403.shtml] I just uploaded a dummy 403.shtml file to just not fill up cpanel error log and see what I can catch that is causing this error.
I didn't see any issue with site CPU usage.
