I was hoping that a Sun expert would show up and tackle this question. But I guess I'll give it a try.
First, yes you modify /etc/system and reboot...no need to build a new kernel, it gets built on the up.
But your syntax looks wrong. We have stuff like:
set semsys:seminfo_semmni= 4096
in our /etc/system. Any values in the seminfo structure are going to support system v semaphores.
On hp-ux, maxuprc is the max processes per user with maybe 50 or 100 being typical values. But on Sun maxuprc is the total processes for all users and it is typically set to NPROC - 5. So while you could bump this up, it wouldn't make sense.
If you are getting "can't fork", you surely want to up NPROC. But, just as with hp-ux, NPROC is a calculated value that rides off MAXUSERS. So my guess is that you want to increase MAXUSERS, which will increase NPROC, NFILE, NINODE, NCALLOUT, and NCLIST all at once.

config.guess
CONFIG.GUESS(1) User Commands CONFIG.GUESS(1)
NAME
config.guess - guess the build system triplet
SYNOPSIS
config.guess [OPTION]
DESCRIPTION
The GNU build system distinguishes three types of machines, the `build' machine on which the compilers are run, the `host' machine on which
the package being built will run, and, exclusively when you build a compiler, assembler etc., the `target' machine, for which the compiler
being built will produce code.
This script will guess the type of the `build' machine.
Output the configuration name of the system `config.guess' is run on.
Operation modes:
-h, --help
print this help, then exit
-t, --time-stamp
print date of last modification, then exit
-v, --version
print version number, then exit
ENVIRONMENT VARIABLES
config.guess might need to compile and run C code, hence it needs a compiler for the `build' machine: use the environment variable
`CC_FOR_BUILD' to specify the compiler for the build machine. If `CC_FOR_BUILD' is not specified, `CC' will be used. Be sure to specify
`CC_FOR_BUILD' is `CC' is a cross-compiler to the `host' machine.
CC_FOR_BUILD a native C compiler, defaults to `cc'
CC a native C compiler, the previous variable is preferred
