100% CPU usage

I’ve had a constant problem for some days with the Googlebot. It seems to get stuck in the calendar and the CPU usage is 100%. I tried following this advice: https://time.ly/resources/troubleshooting/limiting-excessive-google-crawls/ (replacing “calendar” with the danish term “begivenhed”. The only thing that helps is blocking the bot in .htaccess – but that’s no so helpfull.
