DHCP Failover and clients attempting to renew every 6 seconds.

[Cory Meyer]

I'm running into an issue with my newly implemented DHCP Failover
configuration on DHCP-3.0.5.  I've got a good number of clients
attempting to renew their lease every 6 seconds.   Odd thing is that
the default-lease-time is set to 7200 and the max-lease-time is set to
14400.   I've verified with Tcpdump/dhcpdump that the DHCPACK does
contain the correct lease time.

Any ideas?
Thanks,

Cory

one-lease-per-client true;
option domain-name "myfakedomain.com";
default-lease-time 300; max-lease-time 300;

include "/etc/dhcp/failover.conf"
include "/etc/dhcp/pools.conf"


## /etc/dhcp/failover.conf -- Example
failover peer "dhcp" {

  load balance max seconds 5;
  mclt 3600;
  # Split of 0 will not load balance.
  split 0;
}


## /etc/dhcp/pools.conf -- example
 subnet 10.1.112.0 netmask 255.255.252.0 {
        pool {
        failover peer "dhcp";
