Re: Device polling heavy traffic

Hello,

Sorry for omitting the esential details about my system.


You can find my dmesg at:

http://pastebin.com/479977

I'm running:
FreeBSD 6.0-RELEASE-p1

Here is my kernel configuration:

http://pastebin.com/479981


I wasn't there when the panic happened, I just noticed the load average 
was increasing (with polling disabled); and it kept increasing until the 
machine become unresponsive. After 1-2 minutes I observed it had 
rebooted itself.

Now  I have polling enabled on it, I have kernel.idle.poll set and a 
latency of 1-5 ms inside the local network.
But on the 3 links I have spoken of, altough they are not full I have 
between 1-5 ms and 20-30 ms (when the number of packets passive through 
the machine increases).
