Transient error with sendto in send_ip_packet

On one of my scanning machines I periodically get sendto in send_ip_packet: sendto(9, packet, 44, 0, w.x.y.z, 16) => Operation not permitted And I have been unable to track down the source of the error. I know strict iptables rules can sometimes not permit certain packets but this error occurs with and without any iptables rules. Any insight into what could be causing the problem would be much appreciated. Here is some information that may be needed: $ nmap --version Nmap version 4.11 ( http://www.insecure.org/nmap/ ) $ uname -a Linux burninator 2.6.17-gentoo-r5 #1 SMP PREEMPT Thu Aug 17 21:06:35 UTC 2006 x86_64 Intel(R) Xeon(TM) CPU 3.40GHz GNU/Linux $ gcc --version gcc (GCC) 3.4.6 (Gentoo Hardened 3.4.6-r1, ssp-3.4.5-1.0, pie-8.7.9) CFLAGS="-O2 -march=nocona -pipe" Here is an example of a scan that generates these errors. The issue is *not* related to "-P0". # nmap -P0 -A -v -p- -T4 --min-parallelism 96 --min-hostgroup 128 <several thousand ips> Please let me know if there is anything else I can provide.
