Excessive Receive Errors - Trunk 6513 <--> 6513

While looking at port stats of my a core 6513 with Solarwinds Network Performance Monitor I noticed 4 of the trunk ports ,going to an adjacent 6513, are throwing hundreds of thousands of receive errors PER MINUTE. Using the command "show channel <channel-id> mac" I see the In-Lost counter climbing like crazy. Here are the counters twice...seperating each count by 15 seconds to give you an idea of the rate

Output 1:

CORE-A> sh channel 1730 mac
