Desktop App - too many files open

📱 Desktop & mobile clients 💻 Desktop

Hi

My client application doesn’t sync, it sends an error of too many files open.
I am using Ubuntu 20.04
the client works with 18.04

Is it client side or server side that could be causing the issue?
I tried amending how many files can be open on the client, but was no solution to the issue, so i have reverted to original file setting of not stating a number. as below

/etc/systemd/user.conf
DefaultLimitNOFILE=65536

/etc/security/limits.conf
*       soft    nofile  65536
*       hard    nofile  65536

Any help or point in the right direction will be much appreciated.

I am having the same issue since a few days ago. Is there any way to fix it?

I have found a workaround for the time being. IT ISN’T PRETTY.

1:
You can gradually increase the amount of files the client syncs. e.g. I syncd my documents first, then reopened the settings and clicked the videos tick box and re-sync’d, then did the same with the pictures etc.

it got to the point where it was taking ages so I tried the next step

2:
goto the following and add the following

/etc/security/limits.conf

*         soft    nofile      500000
*         soft    nproc       500000
*         hard    nproc       500000

/etc/systemd/user.conf
DefaultLimitNOFILE=500000

/etc/systemd/system.conf
DefaultLimitNOFILE=500000:524288

ensure the system is updated and restart. seeems to be working now, but only after an update, before it would just crash.

I also solved this problem by adding the following line to the config.php file of the Nextcloud server :
'bulkupload.enabled' => false,
I have experienced this problem on several servers with different configuration and Nextcloud version 25.0.2.
The function is an optimization for small files, but the server still work pretty fast.

Still working perfectly.

I solved the same thing on Kubernetes, so I’ll just add how to add it to the values file:

  configs:
    custom.config.php: |-
      <?php
      $CONFIG = array (
        'default_phone_region' => 'CZ',
        'default_timezone' => 'Europe/Prague',
        'bulkupload.enabled' => false,
        'default_locale' => 'cs_CZ',
      );
  strategy:
