Seems like a persistent routing loop.  One possibility I've
heard about is the persistent routing loops that can occur if an internal
router is not situated topologically close to its BGP route reflector:

Does anyone have any idea of if/how often these types of persistent loops
occur in practice?  I guess there would be no way to really tell if this
was the cause without having some knowledge about the internal topology...
