Howdy! I am hoping y'all could help me add more debugging to a FreeBSD 14.=
x based router/gateway. The device has two ix(4) NICs for the WAN/LAN. Per=
iodically the device stops routing traffic entirely, but the machine is st=
ill online and interactive.

What is particularly interesting is when I console into the machine I can =
still send traffic out from the device over the WAN interface, but anythin=
g that relies on the gateway seems to fail. I.e. routing to any host on th=
e LAN interface (ix1) no longer works.

`service routing restart` does nothing, `service netif restart` also does =
nothing. Downing the ix1 interface and bringing it back up does nothing.

A reboot however does puts it back into working order. =



On one instance the console had a lot of arpresolve "cannot allocate llinf=
o" errors, chasing that rabbit led nowhere.

Because this freezing behavior is intermittent but _does_ seem to correlat=
e with higher network utilization, I'm wondering if there are debugging lo=
gs I can enable, or a way to inspect driver specific counters that could b=
e overflowing, etc?

I'm open to any recommendations that prevent me from setting up a cron eve=
ry minute to validate connectivity or reboot the box! :)


Cheers
