"session was cancelled" on large file xfers

[Ken Hardy]

I've seen a couple mentions of trouble w/ large files in the list
archives, but nothing that seems to resolve this problem...

When trying to move or copy largish files (~ >1MB) with WinN using
Samba 1.9.18p10 on a Sparc Solaris 2.5 system, things hang for a while
and then a dialog box pops up saying "Cannot copy {filename}: The
session was cancelled.

I've tried setting "oplocks = no", but I still see a lot of this in the
log file when the failure occurs:

'pdir' is a symbolic link to a directory on another physical volume
on the same machine.
