This is a DMVPN network where all the 250 neighbors are stubs.

RE: large number of OSPF neighbors
Obiously, you have a design issue. At one time, Cisco recommended max of
100
routers in an area. I don't know what the number is, but you need a good
core network design and 250 routers in one area is in my opinion "BAD,
REALLY BAD." When 1 router's link flaps all other routers in an area need
to
recalculate and reconverge.
Break up the areas, back bone, stubby, not so stubby, etc.
I'm assuming that most routers have only one path back to the core router,
break them into managable stub areas.
