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 ;-)
