	Using Samba 2.2.x series implies that you are pretty much
on your own. It is ancient code, deprecated by Samba 3 series and
not maintained any more. It means that it could be a bug that it
is not going to be fixed by the Samba Team.

	It sounds like oplocks. I can't remember exactly how it
works in 2.2 and I don't have any machines with manpages and
documentation from that version. But that should be the way to
go.
