This is almost certainly due to oplocks on the client. To
prevent this either turn off oplocks on the Samba server
(oplocks = no on the share definition) or use Linux, which
has a kernel that natively supports oplocks. Hmmm. As you're
on a SCO system I'd definitely suggest the latter. Using a
system whose author shows a predilection for suing their
own customers isn't a good idea...
