The Nextcloud client syncs every few seconds.

I hope I’m in the right place here. I’m dealing with an issue involving the Nextcloud client and client push.

The problem is that the Nextcloud client tries to sync every few seconds.
This leads to synchronization conflicts and errors.
If I disable client push, the constant synchronization attempts stop.
The downside is that file changes are then no longer synced promptly from Nextcloud to the client.

I have tried the following:

Disabling files:scan in cron for external file changes. No improvement.
Adjusting the fstab settings, since my data is stored on an SMB share. No improvement.

I documented all of my troubleshooting attempts here.

Unfortunately, the community has not been able to help me either.

Steps to reproduce

1. The Nextcloud client syncs every few seconds.
2. Disable client push and the constant syncing stops. However, files changed in Nextcloud are then no longer transferred promptly.
3. Re-enable client push, and it stops syncing every second. But as soon as a file is changed in Nextcloud, the whole thing starts over again and the sync client wants to update every few seconds.

Expected behaviour

Tell us what should happen

Actual behaviour

Server configuration

Web server: Nginx

Database: Maria

PHP version: 8.4

Nextcloud version: 33.0.2

If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your Nextcloud installation folder

Start by reproducing the repeated client-push synchronization described in the issue, with client push enabled and disabled, and review the linked troubleshooting report for context. The issue does not name a source file or test and leaves expected behaviour unspecified, so a maintainer should first define the notification behaviour and diagnostic evidence needed before implementation.
