Sorry for the late reply; I was out all weekend.
We can't reproduce the problem because we don't have
another Oce' and Opus setup ($$) to test it on, but in
essence:
No corruption on Netware, no oplocks.
Corruption on Samba with oplocks.
No corruption on Samba, no oplocks.
Yes, turning off all oplocks was the only change made.
2 Samba authors and a Google search confirmed this
kind of corruption.

Still, it's corruption, and the user ought to be made
aware. I would like (at least) to submit a
documentation patch. It might have saved us grief.
