Public bug reported: in /etc/init/isc-dhcp-server.conf (near end of file)
exec dhcpd -user dhcpd -group dhcpd -f -q -4 -pf /run/dhcp- server/dhcpd.pid -cf $CONFIG_FILE $INTERFACES in /etc/init.d/isc-dhcp-server # try to read pid file name from config file, with fallback to /var/run/dhcpd.pid if [ -z "$DHCPD_PID" ]; then DHCPD_PID=$(sed -n -e 's/^[ \t]*pid-file-name[ \t]*"(.*)"[ \t]*;.*$/\1/p' < "$DHCPD_CONF" 2>/dev/null | head -n 1) fi DHCPD_PID="${DHCPD_PID:-/var/run/dhcpd.pid}" The default dhcpd.pid file location differ (should be same). So if you'll try to do: /etc/init.d/isc-dhcp-server restart you'll get TWO dhcpd servers!
