Alright, I have the machine up to 6.3-STABLE #1 now.  I've changed 
subnets on the one card that pushes the traffic.  There is a run down of 
the machine now.  The machine is still having the weird network traffic 
problem of capping at around 100mbps and then dropping to 10~20mbps the 
next minute.  Any suggestions?
