check-status (id) Check status of a given busy dynamic lease, and free it in case of no response

your leases are not 'busy', they are 'bound'

busy - this address is assigned statically to a client or already exists in the network, so it can not be leased
bound - server has received client's confirmation that it accepts offered address, it is using it now and will free the address not later, than the lease time will be over
