Since you did not post any configuration, let me assume that your iBGP peers
are 1.1.1.1 and 2.2.2.2 respectively, and assume router 1.1.1.1 is receiving
ospf default route,
initially iBGP session will come up, but once iBGP routes are received,
routing table will have all (longer prefix) iBGP routes, and iBGP peer
connection will take the longer prefix route which itself is a iBGP route,
this is a race contidition, so iBGP will eventually go down, and all iBGP
routes withdrawed, and iBGP session established again, the process will keep
going and going.
