Is the traffic in question to something directly connected to this
switch and just appearing mirrored to the wrong port or perhaps
broadcast to all of them?   Or is the actual destination on some other
switch where this one shouldn't even be in the path?   If you want to
track the problem down you need to look backwards from the target and
figure out why the switches in between did not learn the correct path.
 It is not likely to be related to the traffic bandwidth unless some
intermediate link is flooded to the point that nothing works.
