Steven,
Had this exact scenario occuring on a 7010 a couple years back. Sorry,
we never did reach resolution on the issue, just jumped to another router.
BUT, I do have a theory and wondered if you could indulge me with a brief
on your topology (you might want to send this off list to
kulriksen@sitestream.net). If you're topology is similar to what I was
using at the time, I may have an answer for you.
