This is probably related to adding some new tunnels, starting BGP sessions with BIRD and adding some routes. A few hours after this change the both routers crashed just minutes apart with identical stack trace. Once the change was undone, the routers operate stable for days. I understand that icmp6_rip6_input's job is to deliver ICMP6 packets to open sockets. In case of my routers the raw sockets would be held by radvd, fping (from smokeping) and some python program I use as a smokeping replacement. Looking at the mbuf at frames 33 icmp6_rip6_input, 34 icmp6_input, 35 ip6_i= nput I can see ICMPv6 Neighbor Solicitation messages. Please find attached kgdb bt output. I have the whole memory dump and I can= get other data from it if necessary. --=20 You are receiving this mail because: You are the assignee for the bug.=
