I find that very strange. cease_adv_pfx_msg is only called if the
DecrementLifetimes prefix option is set, and the preferred lifetime of
the prefix reaches zero, yet your config doesn't have the per-prefix 
DecrementLifetimes flag set, and it doesn't default to on.

Are your lifetimes decrementing, even though the DecrementLifetimes
option isn't enabled? What is the behaviour if you do enable it?
