Ever noticed your website go completely white? Both frontend and backend? How long before panic set in? How long did it take you to discover that going to /var/cache/ and doing rm rf * gets the website back?
The annoying thing about this bug is it can randomly happen when you least expect it and you might have to wait weeks to see it again.
The best way to get rid of this bug is to upgrade your Magento version, this bug only seems to exist in version earlier than 220.127.116.11.
If this still continues get in touch and I’ll provide another potential fix.
