dhcpd doesn't acknowledge dhcp requests

[Sean McMurray]

I've removed failover and simplified the config. But dhcpd still ignores 
dhcp requests.
My config now looks like this:

log-facility local6;
ddns-update-style interim;
ignore client-updates;
authoritative;
max-lease-time 300;

subnet 10.96.0.0 netmask 255.248.0.0 {
   log(info, concat(
     "Lease: ",binary-to-ascii (10, 8, ".", leased-address)
     ," Mac: ",binary-to-ascii(16, 8, ":", substring(hardware,1, 6))
     ," Relay: ",option agent.remote-id
   ));
   option routers 10.96.0.1;
   pool {
     range 10.96.1.0 10.96.255.255;
   }
}

subnet 10.104.0.0 netmask 255.248.0.0 {
   log(info, concat(
     "Lease: ",binary-to-ascii (10, 8, ".", leased-address)
     ," Mac: ",binary-to-ascii(16, 8, ":", substring(hardware,1, 6))
     ," Relay: ",option agent.remote-id
   ));
   option routers 10.104.0.1;
   pool {
     range 10.104.1.0 10.104.255.255;
   }
}

subnet 10.112.0.0 netmask 255.248.0.0 {
   log(info, concat(
     "Lease: ",binary-to-ascii (10, 8, ".", leased-address)
     ," Mac: ",binary-to-ascii(16, 8, ":", substring(hardware,1, 6))
     ," Relay: ",option agent.remote-id
   ));
   option routers 10.112.0.1;
   pool {
     range 10.112.1.0 10.112.255.255;
   }
}
