When the maximum number of multicast group memberships is exceeded, a different error will be returned by the system: ETOOMANYREFS A.K.A. "Too many references: can't splice". Indeed, a system file needs patching if that happens. However, it doesn't seem to be the case. I think that this time your routing software just tried to join the "all OSPF routers" multicast group on the same interface multiple times because there were IP aliases assigned to that interface or you used unnumbered p2p interfaces. In the first case it should be harmless while in the second case the error message in fact indicates that your routing software cannot specify an interface by its ifindex to the IP multicast API of FreeBSD.
