This error has appeared since version 18. Currently, version 19.0.4 is installed

I did not find anything like it on the forums. What thoughts are there? thanks

Replaced only the identification data in the presented config.

Is there any reason why you’ve set the parameter ‘memcache.distributed’? For a local installation the parameters should look like this. BTW, using the Redis socket is much faster and doesn’t rely on the loopback network interface but requires the socket ownership to be set correctly:

  'memcache.locking' => 'OC\\Memcache\\Redis',
  'redis' => array (
    'host' => '/run/redis.sock',
    'port' => 0,
    'password' => '<password>',
    'timeout' => 0.0,
  ),

When using the ‘memcache.locking’ parameter, I get a lot of errors. more details in the picture.

Yes you are right it is better to use unixsocket.I set up the server according to the manual, that’s why the ‘memcache.distributed’ parameter was used, in which only the error is described in the topic.

At the moment, reconfigured according to this config.

‘memcache.local’ => ‘\OC\Memcache\APCu’,
‘memcache.distributed’ => ‘\OC\Memcache\Redis’,
‘redis’ => [
‘host’ => ‘/run/redis/redis-server.sock’,
‘port’ => 0,
‘dbindex’ => 0,
‘password’ => ‘secret’,
‘timeout’ => 1.5,
],

Error: count (): Parameter must be an array or an object that implements Countable at /usr/share/nginx/html/nextcloud/lib/private/Memcache/Redis.php#88
is kept for now.
I noticed that it appears when installing applications.

I have been using nextcloud not so long ago, maybe I haven’t figured it out yet.
