[Samba] problem with kernel oplock

[stephane.purnelle at corman.be]

Hi,

We test a software called Safekit.
This software permit to have a replicated FS and can start some apps from 
a particular script.
We use this startup script for starting SaMBa. 

We make this test : 

NODE1 : Samba not actif (SECOND)
NODE2 : Samba is running (PRIM)

open a file with samba and modify it
make swap
I try to save and no possible to save, but if I close the file and reopen 
it it works fine.

On the log file, we have : 

[2007/10/17 12:25:50, 4] smbd/open.c:open_file_ntcreate(1605)
  calling open_file with flags=0x0 flags2=0x0 mode=0760, access_mask =

[2007/10/17 12:25:50, 5] lib/util.c:show_msg(494)

Anyone can explain this little problem ?

Samba 3.0.26a
The shared directory is accesible with a local mount of a NFS share.

thanks
