Hello, here is a real interesting case for NeXT.

I received the report that one of our NeXT is disk full.  So I went out
and checked it.  But the total number I've got for all the local files
is always 200MB less than the disk space.  So where did the 200MB go?

I went on checking the process table.  They are all friendlies.  No bad
guys.  However, two of the process looked strange enough.  It is a pair
of csh and mail processes.  I cannot find anything funny of those two
processes untill I check where did that user from.  The answer is: 
ttyp2 of that NeXT.  What make this so special is there is no body login
from console of that machine at that time.  I myself and that user are the
only guys on that system.  So how the hell could those processes be there?
Again, the total space used by all the processes are only 40M also.  We
still come out 160MB short.  Since the that orphant tty session have been
idled for 11 hours.  I decided to kill them.  Once I did that, boom! All
the missing 200MB came back!

Gosh, could anyone of you who can make a reasonable explain of this for me.
