samba - Jul 2007 - Problems with oplocks (samba 3.0.24, Kernel 2.6.17)

Hi list!

We migrated from FreeBSD 5.2 with Samba 3.0.22 to samba 3.0.24 on Linux, 
Kernel 2.6.17. Some users are running foxpro programms on XP and W2K and have 
problems now concerning locked files. The old FreeBSD server never had such 
poornesses. I couldn?t find a solution searching the web but I tried out this 
smb.conf options:

kernel oplocks = yes
fake oplocks = No
locking = Yes
oplocks = Yes
veto oplock files = /*.DBF/*.dbf/*.MDX/*.mdx/*.NDX/*.ndx/
level2 oplocks = Yes
oplock contention limit = 2
posix locking = Yes
strict locking = Yes
share modes = Yes

Nothing helped. 

The questions now are:

Is it possible to run samba on Linux with clients using dbf without this 
hassles?
If so: How can I accomplish that?

Or is the only/easier way to go back to FreeBSD?

Hints and help would be much appreciated!
Regards,

Oliver

The Linux kernels 2.6.17 - 2.6.17.11 have a bug with kernel oplocks that
hits Samba and shows your symptoms.
A kernel update or "kernel oplocks = no" may solve it.

Kernel update seems not to help - on a school in the neighbourhood my  
collegue had the "oplock" problems with Samba 3.0.22 and kernel  
2.6.21.5. Tomorrow we will know wether "oplocks = no" does help.


Viele Gruesse!
