debug ip routing lots of odd output

topology;

 AREA1-[SW1]----AREA0----[SW2]-AREA2

here is an example below ,  i have two  3560 switches running ospf , both are in area 0 , and in SW2 , the debug ip routing is going crazy,  below routes are IA routes from area 1 .  SW1 is stable.

can anyone explain to me the output and what is possibly happening?
