DHCP deleted reservations?

We recently had a maintenance period where we shutdown our DHCP server for
5-6 hours. Upon bringing the server back up, we found that the DHCP server
lost a number of reserved IP addresses. This resulted in several machine
obtaining an incorrent dynamically assigned IP instead of the reserved IP.
We had to enter the reserved addresses again in order to get it fixed.

Why would the DHCP server do that? Is there something that I may have
missed? It almost seems like it lost the most recent changes and selectively
too.
