Errr - I'd guess what's happening is what the error says :-).
And when I added that message I thought it'd be very clear :-(.

The kernel Samba is running on supports 64 bit fcntl locks,
however the underlying (NFS) filesystem that the files are
being shared from only supports 32 bit locks. Thus the lock
request is being denied.

If these files are only being accessed by Windows users (the
usual case for MS-Office files, unless you have OpenOffice
on IRIX) then you can turn off the mapping down to POSIX locking
by setting the parameter "posix locking = False". No harm done.
