It doesn't answer the question "which files are open?", of course.

The simple answer is to say "rebuild your kernel with a higher MAXUSERS". 100 is a good value; there are problems if you go beyond about 250 in 3.1, but they'll be gone in 4.0. MAXUSERS is a rather silly name for parameters which influence the system globally, including the maximum number of open files. Having said that, you might find that your problem lies elsewhere. You won't know that until you know what files are open (see lsof above) and whether they should be open. I'd guess that if you're using this system as a database server, they probably should be open.
