flood with ng_bridge

[dnr]

can you check flood.gif?(it's denied to send gif's to this conference)

for unknown reasons ng_bridge seems to be working like ng_hub and is 
flooding network even after establishing session between two mac addresses.

using kernel bridge instead of ng_bridge solves the problem, but on heavy
network loads "unknown" packets apear in random directions (this does not
happed using ng_bridge or ng_hub)

os used - only FreeBSD5.3

thank you...
