Until you modify the map, an exclusive lock on the map is overkill. Try using read locks. (See vm_map_lookup.) In the meantime, I can't see any reason why mincore acquires an exclusive lock either. (It never modifies the map.) I'm going to remedy that. Alan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
