I'm running Oracle Enterprise Linux 8.8 as a DHCP server with ISC DHCP
version 4.2.6-46 (from the Oracle distribution).  I'm running webmin-2.021
to help with the administration of this server.  Everything used to
work/display just fine but suddenly, when trying to list the dynamic leases
within a subnet, I get the message, "*The DHCPd lease file
/var/lib/dhcpd/dhcpd.leases does not contain any leases that are active at
the current time."  *If I click on the List all active and expired leases
button, I get the message "*The DHCPd lease file
/var/lib/dhcpd/dhcpd.leases does not contain any leases."*  Clearly, when I
use a text editor on the /var/lib/dhcpd/dhcpd.leases file, all the leases
exist, new clients receive new IP addresses and existing ones are able to
renew successfully.  The leases that _DO_ show up are from wireless subnets
or subnets not directly connected to our campus.  I'm not the only one who
administers this server/service so the Webmin module is really helpful and
currently missed.  Any suggestions for troubleshooting and correcting this
issue.  Everything in the /etc/dhcp/dhcpd.conf file agrees with the current
operation.  Thank you.
