This is still ongoing.
I've tried
- /etc/init/isc-dhcp-server.conf
# The leases files need to be root:root even when dropping privileges
[ -e /var/lib/dhcp/dhcpd.leases ] || touch /var/lib/dhcp/dhcpd.leases
#SM 2015-05-08 chown root:root /var/lib/dhcp /var/lib/dhcp/dhcpd.leases
chown dhcpd:dhcpd /var/lib/dhcp /var/lib/dhcp/dhcpd.leases
if [ -e /var/lib/dhcp/dhcpd.leases~ ]; then
#SM 2015-05-08 chown root:root /var/lib/dhcp/dhcpd.leases~

Title:
isc-dhcp-server fails to renew lease file
Status in isc-dhcp package in Ubuntu:
Triaged
Status in isc-dhcp source package in Trusty:
Confirmed
Bug description:
After raring upgrade, the dhcp server fails to renew lease file when
it tries to (about every hour).
The syslog says:
dhcpd: Can't create new lease file: Permission denied
It looks like a permission problem, because
# chown -R dhcpd:dhcpd /var/lib/dhcp
the above command temporarily solves the issue, until dhcpd is
restarted: at that time, the ownership of the directory and the lease
file is set back to root:root.
