[Samba] inotify_add_watch returned Permission denied

[Georg.Biberger at partner.bmw.de]

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
