dhcpd server config help

[Ernie Luzar]

Hello list;

Yesterday had some guests over and when they tried to connect to my WiFi
with their cell phones I got a lot of these console messages.

Sep 19 09:43:01 mydomain dhcpd: Reclaiming abandoned lease 10.0.10.2.
Sep 19 09:43:01 mydomain dhcpd: Abandoning IP address 10.0.10.2: declined.

The cause of this is the host system dhcp server is trying to allocate a
ip address from its pool that’s already in use. Today I started to 
investigate this matter. I must have mis-configured something. Following 
are the config files concerned. Please review and point out errors. 
Thank You.
