hmmm.. oplock problem on smb craches MS Word ... ?!?

[EFT.Eric Devolder]

We run samba 2.0.3 and it works fine since several weeks, until these
days...
Since two days I get lots of problems with samba. Oplocks seems to cause
troubles, and it crashes MS Word in such messages: "unrecoverable network
error" indefinitely until Dr Watson (under NT).

We run 2.0.3 with samba as PDC. Quite all the clients run NT 4.0. 

Here is the entry I encounter very often in the logs :

[1999/04/14 11:29:52, 0] smbd/oplock.c:request_oplock_break(943)

  request_oplock_break: no response received to oplock break request to pid
1807
0 on port 2384 for dev = 808, inode = 1753116


The config file is very simple, here is a snapshot:
(it is not complete, the sharings are not essential here :) )
