[Samba] Strange locking errors with LabView under Samba 2.2.7 and HP-UX 1 1.11

[Windsor Dave (AdW/MOE2.1)]

Hmmmm....that sounds reasonable.  I have 2.2.7a compiled up and ready to
install as soon as our production test equipment shuts down, hopefully
tomorrow.  I'll post my results as soon as I get the chance.

Thanks!

Dave,

Samba-2.2.7a was released to fix 64bit file access issues. Strongly
suggest you update.
