More background. People may be wondering why this is even an issue for FreeBSD as a router. The answer: the imo_membership array contains members which exist as separate entries for each ifnet in the system, and the system where this was observed to be a problem had a number of ifnet interfaces which was larger than IP_MAX_MEMBERSHIPS (20).
