Hi guys,
Don't know if anyone else is experiencing this on CentOS 6.9, upgrading samba causes clients to be unable to open/read any files and all directories appear empty!
Downgrading and restarting the daemon worked for now as a workaround. Behavior is noted on Win10 and Linux clients.
The problematic version in question:
