That is a very very ancient version of code for this platform - in fact 
it was the first branch of code ever even made for these switches. 
There were some pretty rough edges around the earlier releases but it 
has been getting better of late.

I recall having similar problems with something like this, but it was 
quite some time ago - so can you try an upgrade to something more 
recent, say, 15.2(4)S1 ?

Chances are TAC are going to suggest you try this anyway.

Can you also confirm you have the same MTU set on both edge routers and 
can ping at least 1500 end to end?  What does 'show ip ospf interface 
brief' and 'show ip ospf neigh' show as the state of the OSPF on each 
interface?
