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 bird is stopped, traffic forwarding is stopped (since dynamic routes disappers) ? Perhaps your configuration shapes ALL (e.g. network AND local) traffic withing single queue? If so, when queue is full with network traffic even local traffic is delayed ?
this? I can't believe scanning kernel routes is supposed to be this resource intensive? No. It is not any kind of 'intensive' :)
Thanks,
Pawel.
