Agreed.

It's been a while since I did this, but if you "remote login module X" 
where X is the module receiving the traffic (if you're using a DFC) or 
the slot containing the SUP (if you''re forwarding on the PFC) you can 
get access to a bunch of commands that can inspect the hardware FIB.

Sadly, that's as far as my memory goes - normally you'd expect to use 
these under the direction of TAC (and not on a production box!)

You might be able to get some idea of the cause of the fault from doing 
and ELAM capture of a working and failing destination.
