There was a post on cisco-nsp in March 06 describing a similar issue,  
but the poster had noticed that there was high cpu load on some of  
the ospf participants during this bad behaviour.  Do you see this ?

There weren't follow-ups to the message (that I can find), but he was  
running 12.2(25) also.  It may be worth trying a more modern image if  
possible to see if this makes your problem go away.

Thanks,
