DHCP messages bombarding console

I edit the /etc/syslog.conf file to add these lines:

local3.err                                      -/var/adm/dhcp.log
local3.info                                     -/var/adm/dhcp.log
local3.alert                                    -/var/adm/dhcp.log      
local3.warning                                  -/var/adm/dhcp.log      
local3.none                                     -/var/adm/messages

Make sure the dhcp.log file is there. The dhcpd.conf file contains this

log-facility local3;

I restart the dhcpd as well as the syslogd processes. Still I get these
no free leases messages every few seconds into the /var/adm/messages

What is wrong here?

Also use a - in front of the path like so:


This tells syslog to change and write 20 lines at a time. It will
increase performance and lower your drive activity dramatically. Also
good to use with apache logs, etc. With syslog-ng set sync(0) to
