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; ># show ip bgp summary >BGP router identifier xx.yy.zz.ss, local AS number XXXYYY >RIB entries 683010, using 63 MiB of memory >Peers 3, using 18 KiB of memory >Peer groups 3, using 96 bytes of memory > >Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd >ip1.1.1.1 4 1680 105169 44819 0 0 0 01w2d04h 2265 >ip2.2.2.2 4 5585 101800 89437 0 0 0 1d21h50m 1698 >ip3.3.3.3 4 1680 3870780 44813 0 0 0 01w4d11h 362157 > >Total number of neighbors 3 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?
