Hmmm, "7% average CPU" for BGP Scanner seems to be normal (my Sup720
does this as well).  Ditto for spikes up to 50%.

I wonder what the remaining 20% CPU are used for.

But anyway: the CPU is not at 100%, so the box isn't having BGP convergence
issues due to "CPU saturation".  Must be something else then.
