The only solution wich may helps you is adding more bpf-Devices in /dev. I pointed out to Okan that if you run out of bpf-Devices (with nmap 3.95, OpenBSD 3.9) nmap also has a lot other problems even if you just wnana scan localhost (wont work anymore... some errors..bla). Updating to 4.03 will fix this (also some mem-leaks but hell what`s going on... OpenBSD does not updated the nmap-port for 3.9-stable..) but you`ll still need to add more bpf-Devices. ;-/ If you´re running 3.95 on OpenBSD it will also crash (like 4.03 does) if you scan multible hosts (class-B nets) with f.e. (on OpenBSD) -T[0,1]. Agressiv-Scan works with 4.03 on my OpenBSD but your nmap does not crash (my does if I do scanning a lot Class-B nets..but "nobody" maintains class-B networks..or? *ironic*) it just claims there`s no free bpf-Device. Running out of bpf-Devices happens if you may have some other programs running already wich take one/many of the (in OpenBSD 10) bpd-Devices. F.e. tcpdump should be such a program or running multible nmap-scans at the same time in background. So simply adding more bpf-Devices with makedev should solve this problem.
