Never delete the dhcpd.leases file with the daemon running. First kill
it, then delete the file, touch it, and only then start the daemon.
Also, from the dhcpd man page:
In order to keep track of leases across system reboots and server
restarts, dhcpd keeps a list of leases it has assigned in the
dhcpd.leases(5) file. Before dhcpd grants a lease to a host, it
records the lease in this file and makes sure that the contents of the
file are flushed to disk. This ensures that even in the event of a
system crash, dhcpd will not forget about a lease that it has assigned.
On startup, after reading the dhcpd.conf file, dhcpd reads the
dhcpd.leases file to refresh its memory about what leases have been
assigned.
