MonadProxy

I had the same issue recently, running the new permissions tool on that share solved it for me, the only instances where it reverted to root is if I tried to reinstall the container that created the share for instance.
 
In the same vein as you I also created a user that's not root in order to access the shares from windows.
 
 

After changing the nvidia driver to production, I did not get the issue again and it's been 3 days. If it happens again I'll just post a new thread with a more detailed syslog.
 
Thanks again.
