Default what does "not found" mean in a DHCPRELEASE context?

I have a CentOS 4.6 server running dhcpd. One of my client devices (a
Panasonic KX-HCM280A camera) is trying to get a lease from that
server. I can see the device accept a lease (it is a reservation),
however it always releases the reservation after about 25 seconds:

Jul 10 10:30:49 stargate dhcpd: DHCPDISCOVER from 00:80:f0:56:46:30 via eth0
Jul 10 10:30:49 stargate dhcpd: DHCPOFFER on 172.31.14.13 to 00:80:f0:56:46:30 via eth0
Jul 10 10:30:49 stargate dhcpd: DHCPREQUEST for 172.31.14.13 (172.31.0.1) from 00:80:f0:56:46:30 via eth0
Jul 10 10:30:49 stargate dhcpd: DHCPACK on 172.31.14.13 to 00:80:f0:56:46:30 via eth0
Jul 10 10:31:16 stargate dhcpd: DHCPRELEASE of 172.31.14.13 from 00:80:f0:56:46:30 via eth0 (not found)

If I remove the reservation and reset the camera, it does the same
thing with a dynamic lease; however in that case the message is

Jul 3 09:48:05 stargate dhcpd: DHCPDISCOVER from 00:80:f0:56:46:30 via eth0
Jul 3 09:48:06 stargate dhcpd: DHCPOFFER on 172.31.9.91 to 00:80:f0:56:46:30 via eth0
Jul 3 09:48:06 stargate dhcpd: DHCPREQUEST for 172.31.9.91 (172.31.0.1) from 00:80:f0:56:46:30 via eth0
Jul 3 09:48:06 stargate dhcpd: DHCPACK on 172.31.9.91 to 00:80:f0:56:46:30 via eth0
Jul 3 09:48:19 stargate dhcpd: DHCPRELEASE of 172.31.9.91 from 00:80:f0:56:46:30 via eth0 (found)

...ie "(found)" instead of "(not found)".

I should mention that I have several other cameras of the same type
which are working, so this is most assuredly a problem with the
camera itself, but I was still wondering:

Does anyone know what dhcpd (or the device) is trying to tell me with this message?

I believe it's saying the device was telling the server it didn't
want to use that IP anymore, and the server logged that it couldn't
find evidence that it leased that address out to that system in
the first place.

The second log entry would be the server seeing that it had leased that
IP out to the system and released it.
