I still gotta side with Marlon on this one...cleaning ladies WILL cause CRC errors. This is networking 101 Bob, I'm disappointed in you...<sigh>

Its on a commercial rooftop on both sides. Ladies from the cleaning union don't go up there. The cabinets are locked. The rooftops are alarmed and on CCTV on both sides. And it was a crappy day so nobody was out there sunning themselves. And it hasn't happened since. :-) I figured it out with further prodding of the network people. Seems the port is throwing a crapload of CRC errors but only intermittently. Sooo.... we will go back and look at the fiber, swap out patch cables, swap out the GBIC and last but not least swap out the radio. Thanks for everyones input. -B- Marlon K.
