You're right is very extrange that a router receive a LSA 4 (summary) through a
NSSA area, but I think the OSPF configurations are correct. Also, the OSPF net
work works fine for several days after you reboot the router, and it seems ther
e is no problem, but ...
Anyway, I attach briefly the ospf configs of the two routers directly involved:
-ABR ROUTER (181.1.3.3)
router ospf 1
log-adjacency-changes
area 0 authentication
area 113 nssa default-information-originate metric 64
area 135 virtual-link 181.1.2.2 authentication-key cisco
network 181.1.3.3 0.0.0.0 area 0
network 181.1.4.0 0.0.0.63 area 113
network 181.1.4.240 0.0.0.15 area 0
network 181.1.5.248 0.0.0.7 area 135
-ASBR ROUTER (181.1.1.1)
router ospf 1
log-adjacency-changes
area 113 nssa
redistribute rip subnets route-map loop2
passive-interface ATM1/0
network 181.1.4.0 0.0.0.63 area 113

I'm not sure about the message, but if your receiving type 4's from an NSSA are
a, something is out of wack given types 4/5 are not permited in NSSA areas. Ar
e you sure you have all your routers connected to the area properly configured
as NSSA?
