Nextcloud is an open source home cloud server. When Memcached is used as memcache.distributed
the rate limiting in Nextcloud Server could be reset unexpectedly resetting the rate count earlier than intended. Users are advised to upgrade to versions 25.0.11, 26.0.6 or 27.1.0. Users unable to upgrade should change their config setting memcache.distributed
to \OC\Memcache\Redis
and install Redis instead of Memcached.
