Error on my new file server

[Michael_Dahlgren_Nie (Michael Dahlgren Nielsen)]

NethServer Version: NethServer 7.6.1810
Module: File server

I have just made a new fileserver, and now when I look in the log of errors I get this list.
Are there anyone who can help me understand them. And maybe fix them

They are harmless and can be ignored.

Cheers.
