Not that I know of.

sysctl kern.maxfiles
then
sysctl -w kern.maxfiles=N

where N is some higher number than what was returned by the first
command.

You might want to recompile your kernel with a higher "maxusers"
setting because that will automagically scale the amount of other
system structures to deal with your high load situation better.
