"Failed to update branch.", "Fast forward merge for repo X is failed.", Head branch update for repo X conflicts with GC."

Hi Seafile Community,

I try to figure out some bugs in my Seafile configuration.
In the Seafile System Admin Panel under “Devices” and “Errors” I find following messages to my libraries.

"Failed to update branch."

In my “seafile.logs” I got this bug messages every few seconds while uploading via windows client bigger tif picture files.:

Fast forward merge for repo X is failed.
Head branch update for repo X conflicts with GC.

I use “Ubuntu 18.04.5 LTS (GNU/Linux 4.15.0-144-generic x86_64)” and “Server Version: 8.0.2 (seafile-pro-server_8.0.2_x86-64_Ubuntu.tar.gz)”.
I host seafile in the Hetzner Cloud with: “CPX31 / 80 GB + 1400 GB / fsn1-dc14”

4 x VCPU
8 GB RAM
80 GB DISK LOKAL
1400 GB SSD VOLUME (system link with seafile data folder in /mnt)

The usage is following…
We upload up to 1TB picture files (multiple jpgs and tiffs). So each file has 2 MB up to 60 MB. The customers get download links with folders up to 36 Files to generate zips from. So zip archives are round about 100 MB up to 2 GB or in some special cases 4 GB or 5 GB. But most of the time 500 MB - 2 GB.

Uploads are only from two windows maschines. The user is identical. They sync different libraries. In use are 2 - 3 Libraries.

The fail message in system admin panel

What does this actually mean?

It would be amazing if someone could help me with this problems! Or giving some advice or tipp for settings etc…

Thanks a lot,
Julian

Can you post the related log messages in seafile.log on the server?

For sure! Thats an excerpt. This is more or less in repetition.

What also could be relevant. Files are “in creation” while uploading. A scanner is creating / building up multiple files. In the hot sync folder. Could this be a problem? Or what does the “branch update” message mean? Is this a big problem?

Sometimes we got messages in the Windows Client like “Server Error”.
And in the System Admin Panel we get multiple times " Failed to update branch.".

Also eventually relevant, I wrote a script for Garbage Collect. So every 5 Minutes it is executed. For when 1 TB is going to be… And the next 1 TB should be uploaded. So that the volume does not run full of data. Is this meant by “conflicts with GC.”?
