We have a 3640 on the edge running 12.0(9.6)S. It has 2 2W1E's with T1-DSU WIC's in it and 1 1FE NM. About once every minute, the FE card stops sending packets for about 10 seconds resulting in a HIGH and very annoying packet loss. Tries 12.0(10.x)S and replacing the FE cards to no avail. Also, the card has stuck 5 or 6 times with the output queue at 240/240 with no network activity until I reboot it. I'm at a loss here. Any ideas?
