[c-nsp] 3550 + 6509-sup720 output buffer failures

I have a 3550 doing basic layer3 routing on a single port to a 6509, 
but the 3550's port (fa0/1) to the 6509 reports a low amount of 
"output buffer failures" and "underruns". I've seen these errors 
before on another 3550 plugged up to the 6509, but I was unable to 
find the cause. It doesn't appear to be causing (any) issues that I 
am aware of, however I have had some customers complain about a very 
low amount of packet loss.

Has anyone had this issue or something similar or how to fix it?
