I don´t see any filters applied on the tunnels and you are enabling ospf trough the tunnel. how do you learn the end point of the tunnel? send us your routing table of both tunnel end points..
As far as I can see you just guessing you should be are having issue with recursive routing...if you learn the end point trough ospf or higher admin-distance routing protocol. you can fix that by denying learning the tunnel end point from the tunnel interface. Configure the following on both tunnel routers * access-list 15 deny host 150.100.78.8 access-list 15 deny host 150.100.78.7 access-list 15 permit any router ospf 1 distribute-list 15 in tunnel 78 * And let me know..
