isc-dhcpd-server fails to start at boot

view story

http://unix.stackexchange.com – I have been running the isc-dhcp-server fine for quite a while. A few days back after an update, it fails to start. I found a few more people reporting similar problems but that was from 2009. I was unable to find the logs of the isc-dhcp-server process either. However, if I manually start the dhcp server as `sudo service isc-dhcp-server start', it runs just fine. The following is the output of dmesg | grep isc-dhcp-server [ 15.267804] init: isc-dhcp-server main process (1201) terminated with status 1 [ 15.267839] init: isc-dhcp-server main process ended, respawning [ 15.334785] init: (HowTos)
