[11.0.9]My seahub log file is filled with errors, help?

Hi seafile community.
I switched to seafile from Nextcloud and have not been disappointed !

For context, I run the docker from the Unraid Community Apps following these instructions: (as I am not allowed to included links, please re-assemble it removing the space)

And this is the way the two dockers appears in my unraid dashboard :

It worked fine since the initial setup. But a week ago, after a server reboot, I noticed that seafile wasn’t working anymore.
The logs were pointing to server getting refused by the db due to the user not being found and connections being aborted.
Errors looked like this (this is what is currently shown in the logs of maria-db):

At the end I just forced update the seafile server docker without changing any settings and the server finally reached the db and everything looked all right.

BUT no:
I noticed a high usage of the seahub log file. And indeed, it is riddled by errors that I don’t understand:

And to add to this mess, let me add that if I stop and start the server, once again it doesn’t work and I need to do a force update again
image

Force update do the process of removing image and re-creating it from the current git version, like any normal update. I don’t know why doing this allow seafile to work thought.

Thank you for reading this.
