Hi,
I have a FBSD router base on version 8.1-RELEASE-p4.

I have 6 Nics,
bce1 - connected to the net
bce0 & em0  are bridged into bridge0 and connected to a switch & another
server
em1 - connected to a server
em2 & em3  are teammed (using lagg0 with LACP) and connected to an intra net

I'm monitoring traffic using MRTG on my side, on the of the other side of
the lagg0 interface using CACTI monitoring my ports.

Today at 13:00 approx i had a sudden fall down of the traffic on the graphs
on all ports.
the strange thing is that no connection was lost, but the traffic like went
down.

I'm running Quagga on this box with BGP between bce1, and lagg0, but the
quagga interface shows no lack of connectivity;

on the logs i had these lines only:
Aug 17 12:59:45 bgpServer kernel: em2: Watchdog timeout -- resetting
Aug 17 12:59:45 bgpServer kernel: em2: link state changed to DOWN
Aug 17 12:59:48 bgpServer kernel: em2: link state changed to UP

anyone ever faced this problem? any ideas how i can track down what happened
there?

Thanks in advance,
