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); } ---Mike -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet since 1994 www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike
