[Samba] Lost Delayed-Write Data { from win2k advanced server to 2.2.5 }

Hi All,
  i have multi threaded client running on Win 2k advanced servers writing to
network shares [ samba 2.2.5 on Suse 8.1 ]. It works fine 
on the test environment with win2k server [ NOT Advanced ]. But on the
Production environment it fails.. The client shows up the following 
errors..
------------------
Sys: W 'Tue May 20 14:30:38 2003': MRxSmb - " {Lost Delayed-Write
Data}
The system was attempting to transfer file data from buffers to 
_Device_LanmanRedirector.  The write operation failed, and only some of 
the data may have been  written to the file.  " 
-------------------

i bumped up the log level to 5 . and this is the trace for one file [ which
is broken ]..

from the logs i see that some one else is also trying to open the file, but
there are no other processes trying to do that. 
Aside from this, 
 1) i also tried disabling large readwrite [ cuz my processes are writing
files to the order of 4 GB ] ,
 2) also tried disabling the oplocks.
these didnt help.

Has anybody faced this kinda of problem. 
Any ideas to solve this problem are highly appreciated.

Thanks
