The message itself, correct.  The flapping sessions observed on some
code, the long path is indeed triggering some bug. It is immaterial 
if it is the revival of an ld bug or a new one, there are folks 
flapping over this (and related) paths.  Providers without some level 
of sanity filters (really need many-multiples the current diameter of 
the net?) should be shamed into limiting their customer's prepends.
