DHCP Lease expiration only minutes after lease start

stvkellogg
I'm using a Sophos UTM425 with firmware version 9.205-12.

My DHCP servers are set with lease length of 86400 but in the IPv4 lease table I'm seeing the expiry just minutes or even seconds after the lease start, in some cases the same time as the lease start.

I haven't had anyone complain about being kicked off and I don't see lots of new leases for each client, but I was wondering if anyone could explain why the expiry time/date is so soon after the lease start time/date.

Thanks,

Steve

    Screenshot?  The lease start and lease stop columns would be enough.

    How do the files from the dhcp server software look?

    These locations are from 9.113:
    dhcpd.conf location: /var/chroot-dhcps/etc/dhcpd.conf
    dhcpd.leases location: /var/chroot-dhcps/var/state/dhcp/dhcpd.leases
