The DHCP daemon could be killed or the system could crash after the lease database has been renamed to the backup file but before the new file has been written. If this happens, the dhcpd.leases file does not exist, but it is required to start the service. The DHCP service could write into the log file – so there should be no permission problem. Still only the line with DHCP event id 02 and “audit log paused” was written. Restart of the DHCP service did not help.
