PfSense 2.0 is taking a long time to react to ARP replies.

I want to post this here before I go to redmine to file a bug. Maybe something is wrong with my configuration. Basically, I have arp responses coming in on a vlan interface, but pfSense doesn't add an entry to its arp table corresponding to the arp reply until quite a long time has elapsed.

If on pfSense I run "ping 10.0.22.23", a packet capture shows

Who has 10.0.22.23? Tell 10.0.22.3
10.0.22.23 is at xxx:x (the x's are really hex numbers, naturally)

I see this sequence 10+ times until I finally see
Echo (ping) reply

This isn't host specific, although both of the hosts I've tried are running Debian Lenny.

My configuration is quite complicated. I can post any details. I have 9 VLANs on bge0, and those are the only interfaces in use.

PS I've only noticed this problem only on one vlan interface. It has a static IP address and no gateway. I don't think there's anything special about it. It doesn't have any gateways or routes assigned to it.

you have other VLANs that work fine? Where are you seeing that ARP, on the VLAN interface itself or the parent? May also want to check the parent with -e on tcpdump to ensure those have the correct VLAN tag from the switch.
