Let me finish that thought.  The MCLT must only be specified in the
primary servers configuration file.

I noticed that the mclt time is set on both the primary and secondary
servers.  It must only be specified on t

Folks,

We upgraded from dhcpd 3.0.5 to 3.1.0 on two failover peers last night.

We had a problem afterwards detailed below.  I suspect there may be 
either a problem with my failover config or some compatibility issue 
with the format of /var/state/dhcp/dhcpd.leases from 3.0.5 to 3.1.0 that

caused the issue.  Anything jump out at anyone?

Here is my failover config:

Server 1:

failover peer "patriot" {
        primary;
        address 10.0.0.1;
        port 519;
        peer address 10.0.0.2;
        peer port 520;
        max-response-delay 5;
        max-unacked-updates 5;
        mclt 1800;
        split 128;
        load balance max seconds 5;
        max-lease-misbalance 2;
        max-lease-ownership 1;
        min-balance 1800;
        max-balance 1800;
}

Server 2:

failover peer "patriot" {
        secondary;
        address 10.0.0.2;
        port 520;
        peer address 10.0.0.1;
        peer port 519;
        max-response-delay 5;
        max-unacked-updates 5;
        mclt 1800;
        load balance max seconds 5;
        max-lease-misbalance 2;
        max-lease-ownership 1;
        min-balance 1800;
        max-balance 1800;
}


Anyone know why these particular messages would occur at the rate of 
several hundred per second until the 2.0gig syslog file limit was
reached?
