Reusing Expired leases

[Iahmad]

apology in advance if this topic is already discussed.
in pfsense 2.3, DHCP is not reusing the expired leases.

please suggest any setting or method to resolve this..

Expired leases will be reused if/when they're needed. dhcpd's behavior is to not hand out an expired lease again until all the leases that haven't yet been assigned are exhausted.
