Problem solved. Thanks.
A whole lot of people have already replied. A couple of them pointed
me to the solution. There were a couple of big files in a directory
that was under a mount point. Those files occupied valuable space,
but du and ls couldn't see them. I was able to find them by using
dump to make a copy of the filesystem somewhere else. Then it was
simple to use du on the copy to find big files.
A couple of people also pointed out that I confused du and df in my
description of the problem.

My original question:
---------------------------------------
There is an IPC (SunOS 4.1.4) whose / filesystem is full, and I can't
find the offending file(s). I tried all the obvious stuff, to no avail:
* Log out everyone and kill all user processes.
* Reboot
* fsck
* lsof
* fuser
Still df can find only about a quarter of the stuff that du says is
there. What next?
