 % DHCPSRV_LEASE_SANITY_FAIL The lease %1 with subnet-id %2 failed subnet-id checks.
+This warning message is printed when the lease being loaded does not match the
+configuration. Due to lease-checks value, the lease will be loaded, but
+it will most likely be unused by Kea, as there is no subnet that matches
+the IP address associated with the lease.

+% DHCPSRV_LEASE_SANITY_FIXED The lease %1 with subnet-id %2 failed subnet-id checks, but was corrected to subnet-id %3.
+This informational message is printed when a lease was loaded, but had
+incorrect subnet-id value. The lease-checks parameter was set to a value
+that told Kea to try to correct the problem. There is a matching subnet,
+so Kea updated subnet-id and loaded the lease successfully.
 
 % DHCPSRV_LEASE_SANITY_FAIL_DISCARD The lease %1 with subnet-id %2 failed subnet-id checks and was dropped.
+This warning message is printed when a lease was loaded, but Kea was told
+(by setting lease-checks parameter) to discard leases with inconsistent
+data. The lease was discarded, because either there is no subnet configured
+with matching subnet-id or the address of the lease does not belong to the
+subnet.
 
 % DHCPSRV_MEMFILE_ADD_ADDR4 adding IPv4 lease with address %1
 A debug message issued when the server is about to add an IPv4 lease
