      Hi All,

      I am also facing the same issue while launching dhcp relay process (dhcrelay). Whenever i configured a server address on relay machine i faced this issue. There is no process names as dhcpd on my machine.
      Its very annoying to see these error logs because sometimes we got this error sometimes not.

        Something must already be running. Post the full output of the following command:
