samba - Jun 2020 - inotify_add_watch returned Permission denied

Hello,

We are using Samba 4.10.16 as a file server on a linux box with SLES 12. All is
working fine with our NAS NFS Shares. We are now trying to integrate new NFS
Shares from an archive provider, but samba gets crashed when a client tries to
access files on these shares. New start of samba is required! In the smbd.log, I
see these entries:

Any idea what this mean? Which permission is missing? So I can contact the
archive provider to solve this issue.
Any help would be appreciated.

Kind regards

OK, Samba shouldn't crash, but nothing in what you have provided shows a 
crash, so do you have logs that show the 'crash' ?

It might help if you can also post your smb.conf file.
