The other thing I've found about traffic type is how sensitive
netflow is. I was running it for a while, then I got a co-lo customer
that had a lot of UDP traffic with small packet sizes and rarely more than
a few packets between the same src/dest ip/port (much like DNS
queries). It was enough to flatline the box and cause it to crash.
