Hello there colleagues.
After upgrading one of our gateways I'd encountered reproducible
kernel panics in multicast-related situations. processes involved are
mrouted (from base system) and ospfd from zebra-0.92a_1
FreeBSD gw-f.rinet.ru 4.6-STABLE FreeBSD 4.6-STABLE #2: Wed Jul 10
15:05:26 MSD 2002 root@gw-f.rinet.ru:/var/obj/lh/src/sys/gwfn i386
I suspect options MROUTING being "The Evil" [tm], but had no time to check
it thoroughly (it's production gateway, you know, so now I'd simply stick
it out with about 40 statics both there and on border Cisco ;-)
kernel config file follows (it's 4-ethernet router + COM multiport console
server)
Any thoughts?
Sincerely,
D.Marck [DM5020, DM268-RIPE, DM3-RIPN]
