Traffic graph shows 2X the actual traffic.

FreeBSD 8.3-RELEASE-p11

Configuration

em0 - wan interface
em1_vlan10 - private lan interface
em1_vlan20 - DMZ lan interface

One PC on private lan is streaming video from Internet. As can be seen in attached screen shot traffic on private LAN interface is roughly 3mbps but graph shows 6mbps!!! Why does graph show twice the actual traffic?

WAN interface shows correct traffic at about 3mbps on graph.
