Agreed. But it only happens on one end, no error messages from the other
end. And it happens very randomly throughout the the network. Weve got
about 40 T1's and it happens to one T1 then might not happen again for
months. But about 1/2 the 40 T1's get it at sometime or another very
randomly dispersed over time and geography. Thats what leads me to belive
a IOS bug in false positives - running 11.1(4), soon upgradeing to
11.1(15) - just wondering if anyone else has seen somthing similair.
