Thanks to all who responded.  Original problem was the who 
command was showing users who werent actually logged in at 
the present time.  Upon looking at their processes, there 
were no processes active either, but they still showed up 
as being logged into the system.  The problem began just 
after upgrading to 4.0d.  
The solution seems to be with the /usr/adm/utmp file.  
Apparently this file was corrupted.  I wiped out the file 
and recreated it and so far everything seems to be back to 
normal.
