Re: Latency spikes on FreeBSD 8.2 with kernel scan function.

Hi,

bird has nothing to do with kernel packet forwarding. It is control plane software. Do you have some kind of shaping (dummynet, altq) configured? I do have dummynet configured, but like I said - every 20 seconds network freezes for about 0.5s. Guess what happens every 20 seconds... You got it! Protocol "kernel" scans the kernel routes. Also, after /usr/local/etc/rc.d/bird stop, problem is gone. What could be causing this? I can't believe scanning kernel routes is supposed to be this resource intensive?

Thanks, Pawel.
