I've seen it on all of our 2948/2980 switches....
It seems sporadic and happens on various versions of the imge...
We've also noticed that a SPAN port does not always pass all traffic (even
on a lightly loaded switch)...
The "leakage" I assumed was normal...
The SPAN issue allowed me to convince the layers above that we needed a
"tap" to ensure sniffers were not missing traffic....
