f.sell · May 6, 2022, 7:14am

After migration to Nextcloud 24 (4 instances) are some directories are disappered in the Browser.
All 4 instances show this issue. One instance in the root directory, some others in subdirectories.
All affected directories have data >1GB in it.

Linux clients seems to work correct. All directories are seen and snchronisised.
On Winows clients users reports an error. I don’t know the exacte message.

php occ files:scan --all does’nt help.

Browser: Firefox https://xxx.de/index.php/apps/files/

Bug Report this to Nextcloud server github

P1NN3N · May 26, 2022, 6:46pm

Had the same issue on 24.0.1, I replaced Memcached with APCu as local memcache in config.php and now web frontend works again.

Antonio_23 · May 30, 2022, 1:34pm

Hello! Faced the same problem. Can you tell us more about how you fixed this problem?

P1NN3N · June 4, 2022, 9:50pm

This workaround is only tested on Ubuntu 20.04 where Memcached is set as local memcache.

In your Nextcloud config.php file change the line reading
'memcache.local' => '\OC\Memcache\Memcached',
to
'memcache.local' => '\OC\Memcache\APCu',
and be sure to remove the lines containing the Memcached address array, in my case they looked like this:

'memcached_servers' => 
  array (
    0 => 
    array (
      0 => 'localhost',
      1 => 11211,
    ),
  ),

Also, make sure php-apcu is installed. Finally restart web server.

Hi everyone,

I changed config.php to:

…
‘filelocking.enabled’ => true,
‘memcache.distributed’ => ‘\OC\Memcache\Redis’,
‘memcache.locking’ => ‘\OC\Memcache\Redis’,
‘memcache.local’ => ‘\OC\Memcache\APCu’,
‘redis’ =>
array (
‘host’ => ‘localhost’,
‘port’ => 6379,
‘timeout’ => 0,
‘password’ => ‘’,
),
…

It works fo me in all NectCloud - instances on my server.

Thanks a lot

This also fixed it for me. Did anyone put in an issue for this on Github?
