I have just encountered the same problem after upgrading to 21. I’m not stuck in maitenance mode, but cron always runs out of memory. For me also commenting out `memcache.local' => '\\OC\\Memcache\\APCu',` from ` /var/www/nextcloud/config/config.php`, letting the cron job run, and then uncommenting it again seems to have resolved the problem.

EDIT: actually uncommenting again brings the problem back
