Plz check your neigbor link wherether they are fluctuating and check for error in connected interface.

Seems that it has many neighbors and neignborship is continously fluctuating.

I checked that at first stage but that is fine. there is no fluctuation.

routing table is getting converged at every 3 minutes

and this is asbr for that area

As a drastic measure you could issue "clear ip ospf process" however this would reset all adjacencies and potentially cause a temporary outage whilst the network reconverges.
