attic_server::error: Storage error: Storage error: Failed to create directory /var/lib/atticd/storage/5/5b: Permission denied (os error 13)

I have a strange error that I cannot explain. After a certain period of time when everything is running smoothly, the following error appears in the journal logs:

The file attributes also look ok as far as I can see, user is atticd and rwx is set.

drwx------  2 atticd atticd  92K  3. Dez 00:33 40

The interesting thing is that the directory exists. There is also still enough memory and inodes available. After a systemctl restart it works again.

Have I overlooked something? In any case, I don't think it should output a rust trace either way.
