On a RELENG_8 box from aug 25th, I started seeing a constant spew of
Aug 31 00:17:46 gate8 kernel: if_rtdel: error 47
Aug 31 00:18:29 gate8 kernel: ifa_del_loopback_route: deletion failed
Aug 31 00:18:29 gate8 kernel: if_rtdel: error 3

What do they mean and how can I find the cause of it ? The box acts
as an LNS with about 700 ng interfaces with mpd5.5. ipv6 is enabled
on this server as well, so I am guessing it might be related to ipv6
as I havent seen it on the other LNS boxes that have the same setup,
except no ipv6. It was happily running for a few days until this
error started showing up ?
The error seems to be in sys/if.c
if_rtdel(struct radix_node *rn, void *arg)
{
struct rtentry *rt = (struct rtentry *)rn;
struct ifnet *ifp = arg;
int err;
if (rt->rt_ifp == ifp) {
/*
* Protect (sorta) against walktree recursion problems
* with cloned routes
*/
if ((rt->rt_flags & RTF_UP) == 0)
return (0);
err = rtrequest_fib(RTM_DELETE, rt_key(rt), rt->rt_gateway,
rt_mask(rt), rt->rt_flags|RTF_RNH_LOCKED,
(struct rtentry **) NULL, rt->rt_fibnum);
if (err) {
log(LOG_WARNING, "if_rtdel: error %d\n", err);
}
}
return (0);
}
