Were you running CEF by chance?
If I had been in your shoes, I would have suspected CEF,
and done a 'clear adjacency'. Whenever I see strange network issues
that seem to follow specific hosts or subnets, I have in the past
suspected CEF and have turned out to be right about 90% of the
time.
I wonder if what you guys are seeing is maybe a CAR + CEF
interaction issue?
Just a thought.
