[lug] 2.4.20 LFS problem

[Gregory W. Seker]

I'm having a large file support problem with 2.4.20 Kernels.
  -- If I copy a 4gig file from a Linux NFS Server mount to a local
partition, all is fine.
  -- If I copy a 4gig file from a Windows NFS Server mount, I get permission
denied (after 2.1gig)
        (smaller files are successful).

/etc/mtab:
   /dev/hda6 /mnt/data reiserfs rw,nosuid,nodev 0 0
   blue:/nfs /export/bluenfs nfs rw,addr=192.168.20.37 0 0
   black:/export/nfs /export/blacknfs nfs rw,hard,addr=192.168.20.110 0 0

cp /export/bluenfs/BIGFILE         /mnt/data --> Permission denied (after
2.1gig)
cp /export/bluenfs/SMALLFILE   /mnt/data --> succeeds
cp /export/blacknfs/BIGFILE       /mnt/data --> succeeds

glib version 2.2.2
reiserFS version 3.6.25

WHAT GIVES ?

appreciate any direction,
