Hi,
We are running DHCP Server, ISC DHCPd version in a cluster mode. 4.3.1. For
a few days now we are getting the following. Can this possibly be due to a
failure in syncing of the lease pool information between the DHCP cluster
nodes? If so, what is the workaround?
Note: I have masked the IP, MAC, port, FQDN information for privacy/security
reasons.

failover peer "failover" {
secondary;
address 15x.xxx.xxx.5;
port x47;
peer address 15x.xxx.xxx.6;
peer port x47;

max-unacked-updates 10;
load balance max seconds 3;
mclt 3600;
# split 128;
}
