What should i do to avoid these messages from MRTG and dhclient? This happens with some network load on xl0 interface and pf+altq or ipfw+dummynet+statefull rules enabled, even with simple pass rules. Increasing kern.ipc.nmbclusters, kern.ipc.nsfbufs, kern.ipc.somaxconn and net.inet.tcp.sendspace doesn't seem to help. FreeBSD 5.3-RELEASE to 6.0-BETA5 have this problem.
