Hmm, what version of FreeBSD are you using? I don't know the solution
but I wonder if it is related to a similar problem we are having with

Just decided to follow this thread as it seems to be related to some
issues we are seeing as well.
It appears that under heavy packet loads, the kernel cannot pull
packets off the NIC fast enough and thus is slow to free up
descriptors into which the NIC can DMA packets. This causes the NIC

I was poking around some of the in_carp.c code and noticed some odd
behavior due to the fact that ifp->if_ioctl is not always called on

counted in the ierrors field as you said.
Is the Ierrs in the netstat output some other counter? If so, how do
I get the if_ierrors variable from the command line?
