Indeed. Most disappointing.

No. Ours work "most of the time", but as you say an RP CPU spike as low 
as ~50% will take out BFD adjacencies.

What we really need is some kind of supervisor module with a much faster 
CPU. Like the rsp720, only supported in the 6500. Grumble 7600 split 
grumble.

Not a terribly helpful response, but I thought you might like to know 
it's not just you.
