I know there are also quite a lot of other errors. Maybe they are connected in some way.
I have also tried to trace this error. Therefor I added

if (!is_numeric($key)) {
\OC::$server->getLogger()->logException(new \Exception(), ['app' => 'CappedMemoryCacheLine53']);
}

in line 53 in /var/www/nextcloud/lib/private/Cache/CappedMemoryCache.php

I am not sure if this is a bug or a misconfiguration of my system (installed with the official nextcloud vm install_nextcloud_production.sh script). I have never worked with a cache before. I think this is what all these errors are related to.

As the version of the software you've reported this for has reached end of life, I will close this ticket. If this is still happening after an upgrade to the latest version, feel free to reopen
