Strange NFS behaviour under 4.1

[Dan Ehrlich]

On a number of occasions on assorted systems (sun4, sun4c, sun3) all
running SunOS 4.1 strange NFS happening have been observed.

1) Files that are symbolic links are not listed as such.  I.E. ls -lF does
   not show 'l' but 'd' as the first character on the line.

2) Sometimes a directory under NFS mount point will dissapear but it's
   siblings and parent are still accessable.  The file system was mounted
   read-only.  Typing sync on the client cleared this up.

3) Quotas do not seem to be getting updated properly if at all.

Has anyone else seen this behaviour?  Does anyone know if there is a fix?

Thanks,
Confused and concerned in central PA.
