Normally, the DHCP server maintains and uses a reasonable /var/dhcpd/var/db/dhcpd.leases xxx Kilo bytes file. Dd you check the file ?
For some reason, yours went to the "several mega bytes" size. This could be possible, if you have tens of thousands of LAN devices ... But reading it in, to show a web page, will use all memory available to PHP, and it aborts.
Or some other "2.7.0" bug, I can't recall. as that version is pretty old now.

Example : I have about 250 active DHCP clients on my two LANs. My /var/dhcpd/var/db/dhcpd.leases is about 50Kbytes i size.
Also, when I add a new device, this is one of the files I check afterwards, together with the Status > System Logs > DHCP to see if it behaves correctly.

What about upgrading ?

@Gertjan
found the root of the problem to be that the file had whitespaces, so I deleted it and let the DHCP server to re-assign IP's. I thought I had upgraded it to the latest community Version.
