sysctl can do this:

carcharias # sysctl -a | grep sem
kernel.sem = 250        32000   32      128
carcharias # sysctl -e kernel.sem="500 32000 64 256"
kernel.sem = 500 32000 64 256
carcharias # sysctl -a | grep sem
kernel.sem = 500        32000   64      256

I don't have any good document pointer as to what each of the values
here mean, but googling should turn up something interesting.  The
32000 seems like a good sized real-world number, I suspect that is the
system total, and the others might be per-user or per-process.  So I
would just start by doubling the others until you either cannot raise
them any more or it works...
