Lease "not on its queue" Error

[Foggi, Nicola]

Hey Everyone,

We're just working on a failover deployment using 3.1.1 with 2 servers.  It seems that now whenever we add a new pool definition, the failover causes the primary server to exit out, with the following messages:

Jun 28 20:47:54 dhcp-sac-1s dhcpd: Sending updates to failover-peer.

The error occurs after restarting the primary and it does a pool rebalance.  I current add the new pool to the secondary, restart it, then add it to the primary and restart it.

The fix is to remove the lease file on the SECONDARY and restart both which seems to allow it come back up.  Any thoughts?

The failover config is:

  failover peer "failover-peer" {
    primary;
    address x.x.x.x;
    port 520;
    peer address x.x.x.x;
    peer port 520;
    max-response-delay 60;
    max-unacked-updates 10;
    mclt 3600;
    split 128;
    load balance max seconds 3;
  }


  failover peer "failover-peer" {
    secondary;
    address x.x.x.x;
    port 520;
    peer address x.x.x.x;
    peer port 520;
    max-response-delay 60;
    max-unacked-updates 10;
    load balance max seconds 3;
  }

We also saw some times where it would say "backup" instead of "free" in the error message.
