Nothing special. Router 4 is same as 1, in that regard.

On router 1, you could compare the neighbor states for the working and non-working case. Run vtysh cmd "show ip ospf neighbors". If neighbors compare between good/bad cases, compare LS database with vtysh cmd "show ip ospf database router". There is probably a hint in either one of those data sets.
