dhcp-relay for vlan not working?

I have dhcp-relay working perfectly for every physical interface, plus a vtun interface, awesome. However I have a vlan interface that it isn’t working on. I’ve ran wireshark on the DHCP server and no dhcp traffic can be seen coming from clients on the vlan. I verified on the vlan that the traffic is in fact there. There are no firewall rules blocking communication between the vlan and the zone containing the dhcp server. If i set the IP manually for the clients everything works just fine. Am I missing something? is this a bug? Any help is appreciated.

side note, is anyone ever actually on the IRC channel?

Double checking IP addresses is important… wrong server was set.

Can you show your configuration please? I have the same problem with dhcp-relay between 2 different vlans.
