DHCP Server Option 82 denial

[Scott Baker]

We are using Option 82 to make sure our DSL customers only get one
IP address and it's working great except for one customer. We have a
customer who appears to "discover" a new lease, not accept it right
away and then "discover" again. At this point the DHCP server denies
the request:

May 26 09:53:39 dhcp-server dhcpd: DHCPDISCOVER from
00:02:a5:cf:49:75 via 65.182.241.1
May 26 09:53:40 dhcp-server dhcpd: DHCPOFFER on 65.182.239.219 to
00:02:a5:cf:49:75 via 65.182.241.1
May 26 09:53:40 dhcp-server dhcpd: DHCPDISCOVER from
00:02:a5:cf:49:75 via 65.182.241.1: no available billing
May 26 09:53:42 dhcp-server dhcpd: DHCPDISCOVER from
00:02:a5:cf:49:75 via 65.182.241.1: no available billing
May 26 09:53:46 dhcp-server dhcpd: DHCPDISCOVER from
00:02:a5:cf:49:75 via 65.182.241.1: no available billing
May 26 09:53:53 dhcp-server dhcpd: DHCPDISCOVER from
00:02:a5:cf:49:75 via 65.182.241.1: no available billing

I'm assuming it will timeout eventually because the customer didn't
accept the lease. Is that timeout period controllable? If I stop and
start the DHCP server customer gets a lease right away. But that's
not a good solution as it requires my intervention every time this
customer has a problem. The happens regularly with the same customer.

P.S. Sorry for the dupe, I posted this to dhcp-users accidentally
