Memory problem on 3/60

[Mark Ferraretto]

We have 3 Sun 3/60s running SunOS 4.0.3 that just got upgraded from 4Mb to
8Mb.  Since the upgrade users have noticed that when they edit their files
they will find recent changes have not been made, strange characters have
been inserted in their files and one case one user got another user's file
overwritten on his file.  The w/s boot saying 8192k RAM available but they
only test 4Mb when switched on.  The jumpers have been set properly.  It
looks like there is some buffering problem because the files appear OK on
the file server (Sun 4/280 running 4.0.3).  The filesystems are exported
using NFS.

Any ideas?
