I have a 3.8 PF/CARP setup that I can reproducibly screw up simply by
cat'ing lots of text over a telnet session.
It has several subnets, and several NICs, but only 1 subnet becomes
unavailable. Everything else continues to work. There are no errors in
messages, daemon, with PF debug set to misc. Counters all look normal,
same with state table and netstat -m output. The only reason I believe
it's the firewall is restarting it will bring the network back up.
I can't (easily) give direct output from things like ifconfig or pf.conf
as they're both huge and contain information I've been told we don't
want to send out. Hopefully this doesn't prevent anyone from helping me
out.
gem0 - external
gem1 - 120.x
hme0 - 0.x
hme1 - 121.x
hme2 - 119.x
Coming in on hme1 routed through gem1, I can cause everything off gem1
to stop working. The interface shows as up, but nothing works. All other
interfaces work fine. PF continues to work as NAT and external
firewalling still operates.
No errors anywhere, even with debugging turned on in PF. netstat -m
looks the same before and after.
I'm hoping someone can give me a better way to debug this, considering I
can reproduce it. I don't believe it's PF as I can disable and re-enable
it with no effect.
I've disabled ohci using config -e as those were the only errors I was
seeing. Specifically:
ohci0: 1 scheduling overruns
However they didn't happen anywhere near this problem.
