Fred, In this example, there is one database and the two servers are connected to this single database? If this is the case, I don't see why the information would be inconsistent.
If there are two servers, each talking to a different database, with some sort of replication between the database instances, that falls down into an issue of latency of such replication. Kea is already supporting out-of-pool reservations which means that address being reserved will not be hijacked as a result of dynamic allocation (by another client) because an instance of the Kea server "thinks" that the address is available for allocation due to latency of database replication/update. But, from your description I don't know if that is a concern.
