most likely. The kernel parameters you are interested in are:

options SEMMNI=AA
options SEMMNS=BB

...now, the values for SEMMNI and SEMMNS to support NN connections,
I'm not /sure/ of, but for NN==64 I set the following in my kernel

options SEMMNI=32
options SEMMNS=128

There may be other kernel parameters to help you get better performance,
so you might want to dig around the freebsd handbook a bit ;-)
