This looks very much related to a known race in ARP code. See this email and related thread: http://lists.freebsd.org/pipermail/freebsd-net/2012-March/031865.html Ryan didn't check in any patches since, and I failed to follow on this problem due to ENOTIME. I've added Ryan to Cc. Ryan, what's the status of the problem at your side? Did you come to any solution? -- Totus tuus, Glebius. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
