Yes, you can even set the limit on the fly.  To compile it into the kernel,
put a line in your config file that reads

options "MAXFILES=<value>",
e.g.
options "MAXFILES=4026"

To set it on the fly, first (as root)do a

sysctl kern.maxfiles

to see what the default is.

Then do a

sysctl -w kern.maxfiles=<value>

to increase or decrease the value.

I have seen the number set pretty high in production environments, e.g. on
smtp boxes of ISP's.  I've got it up to 4026 on my workstation right now.
It may, of course, blow up any minute.
