oplock errors/copying files between ntfs and samba shares

Hi folks,
having a weird one. files are being corrupted when copied from a ntfs
partition (either local or a network share). files copied from a fat
partion or created on the samba share are working fine. (same files
copied to different locations then to samba)
specifically:
- arcview v3.1 (gis package from esri) can't see it's own files in a
file open
window even though they appear in windows nt explorer - don't know if
they are corrupted or not, however "cmp ntfsfile fatfile" reveals, from
what i understand how cmp works, a single byte diference in the files,
apparently randomly placed in file- don't quote me on that bit though!
there is a significant delay while arcview scans the directory, followed
by the error message below appearing in log.smb
- dimple data files are null filled towards the end of the file for
larger files. very small (~200kB) appear to copy ok
setup details are:
-Solaris 2.6 on pentium 166MMX, disk quotas enabled (but plenty of free
space)
-Samba 2.0.0 compiled with disk quota support (also tried compiling
without -see below)
-NTW and NTS v4.0sp3

smb.log (these error messages received with diskquota support enabled.
when i recompiled without this support, no error messages are logged.
however the behaviour is otherwise unchanged. if i try running at a
higher debug level, the file copy breaks)
