dhcpd.leases file is growing out of control after upgrade

We recently upgraded from dhcp version 4.2.0 to 4.2.5 as part of a
routine OS upgrade. Ever since then my dhcpd.leases is growing
continuously. Before the upgrade the dhcpd.leases would hover around 5
megs, depending on how recently the server has refreshed the on-disk
state. After the upgrade, the file only seems to grow. Over the weekend
my leases file was more than 275 megs! A simple "service dhcpd reload"
dropped the file back down to a respectable 3.7 megs.

Have there been any changes between these two versions that would affect
the size and growth of the leases file? Is there any way to insure the
server is rectifying that file to disk properly?
