I found out what the issue was. As an example, this is valid with "pfctl -f /etc/pf.conf" but will throw "pfctl: DIOCGETQSTATS: Bad file descriptor" with "pfctl -s queue":
queue test on egress bandwidth 1M default This works properly with "pfctl -s queue" as well: queue test on em0 bandwidth 1M default I sent a copy to bugs@ since I doubt this is desired behavior.
