[Samba] Samba Shares Suddenly Look Empty with 3.0.28a

[Andy Liebman]

Does this problem sound familiar to anybody.  On a busy Linux server 
that exports lots of Samba Shares for video editing, upgrading from 
Samba 3.0.23d to Samba 3.0.28a has caused a huge problem.

After several hours of use, ALL exported Samba Shares suddenly appear to 
have NO FILES to ALL CONNECTED OS X CLIENTS. Also, it is still possible 
to log into shares (so to some extent, Samba is still working). But when 
you log in, the shares look empty as well.

There are NO ERROR MESSAGES in the standard "level 3" samba logs. There 
are no error messages in the syslog. smbd seems to be running fine. 
Restarting Samba, and reconnecting to the shares brings the files back.

The problem I am describing has been very reproducible. It's just a 
matter of waiting a few hours and occurs. Reverting back to Samba 
3.0.23d makes the problem go away.

Any ideas?
