I worte:
Hi all,
I have four heavy load mysql database servers which system is 8.0-release
got "panic: rtqkill route really not free" this week. 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?
After four days research we think the problem is between function
in_matroute
and in_rtqkill. This two functions' conflicted at processing RTPRF_OURS
flag
routes. In my opinion, it is a design problem, so I have no idea about how
to
resolve it. The simple way I think is change the panic assert in
in_rtqkill,
treat it as a normal state not assert a panic.
