The following reply was made to PR kern/161899; it has been noted by GNATS. From: Gleb Smirnoff <glebius@FreeBSD.org> To: Steven Hartland <killing@multiplay.co.uk> Cc: freebsd-gnats-submit@FreeBSD.org Subject: Re: kern/161899: Repeating RTM_MISS packets causing high CPU load for ntpd Date: Wed, 8 Feb 2012 16:59:44 +0400 > Any update on this, would have been nice to see a fix hit before > 9.0. If you need any more information please let me know. AFAIK, this is no longer a problem in 9.0-RELEASE or in HEAD. The cause for this number of misses is absense of a route for IPv4 mapped block in IPv6 routing table. Here it is: # netstat -rn -f inet6 Routing tables Internet6: Destination Gateway Flags Netif Expire ::/96 ::1 UGRS lo0 Some rc.d script installs this prefix in 9.0 and 10.0. If it hasn't been merged to stable/8, then it needs to be found and merged. -- Totus tuus, Glebius.
