Running on linux; Suse 7.1. Actually, I realized after more tinkering it
might have been the way I was running it. I was running multiple copies
of seperate subnets (like so:)
./rpcscan_sol -c 20 aa.bb.0.0/16 > aa.bb.txt&
./rpcscan_sol -c 20 aa.XX.0.0/16 > aa.XX.txt&
./rpcscan_sol -c 20 aa.ZZ.0.0/16 > aa.ZZ.txt&
Running a single parent process at a time appears to work fine. It's
plenty fast enough on its own, I should probably just be more patient.
