First of: I've been googleing for about a day, but I'll take any suggestions
for more info.
What I'm trying to do is get as much 1440 byte UDP packets out of an em
device. And when tat works, get as much out of the 7 em devices that this
board has. :)
Currently I run into trouble at 250*174
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
TCP connection scaling, both under 7.2 and 8.0 over a 10 Gb link.
We've been trying to track it down, and if you see it for UDP as well
that may give some clu
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
to dr

Hello,
Starting about a week ago, our primary webserver (then running FreeBSD
7.0) began crashing several times a day, typically during our
higher-load times of day. We have since upgraded to 7.1p7, but continued
to see the frequent crashes.
We are running an apache22 webserver with a lot of per
