Saving files under Sun PC-NFS

[RIE at psuvm.psu.edu]

After editing a file in my PC/AT whenever I want to save the file
directly on our Personal Iris using Sun PC-NFS i get the message
'Disk Full' and the file is not saved. However if i want to copy
a file from the PC hard disk (as diffent from direct memory)
to the PI using PC-NFS there is no problem.
  Has anybody else faced similar problems? I would appreciate your
suggestions to rectify this problem.
