The problem here is the client is changing its DUID so Kea believes the lease was assigned to a different client using the same mac address. To override this behavior the simplest is to use the mac address as the client identifier with flex-id and replace-client-id set to yes.
Another way is to replace on the wire the DUID by a fixed value... Thanks Francis Dupont <[email protected]> PS: DHCPv4 clients have two identifiers: the client-id option and the mac address. If the client-id option has the precedence this can be disabled at the subnet level or higher. There is a RFC too explaining how to deal with this issue when using both DHCPv4 and DHCPv6... -- ISC funds the development of this software with paid support subscriptions.
