We have a gateway set up by OpenBSD have a icmp route redirect function between two subnets, I suspect the FreeBSD panic at trying to delete routes sent from that gateway. So I set sysctl net.inet.icmp.drop_redirect=1, no more panic in past 24 hours. I guess maybe miss some locks or wrong delete route path in 8.0-release. Did any one meet this problem before? -- The Power to Serve
