Dave is wrong. :)

> The bind server seemed to check point its leases hourly (seems to slip back just a little each hour), and while I do see a bind restart in the logs, it was one I triggered at 09:40, there is nothing to indicate server (host or named) at the time of the event (08:18). Nor any indication that DHCPD restarted prior to my manually restarting it later on.

If the problem was caused by the DHCP server you would see the removals 
in the logs. The BIND server did not spontaneously remove anything.

There isn't one. :)
