[CentOS] DHCP Messages

Hi, Im getting this messages in the /var/log/messages about my dhcp 
server. I assume there is nothing to worry about, but just in case I 
have to ask. Are these messages fine? Do I need to specify the interface 
on which the dhcp server should listen to?

...
dhcpd: Multiple interfaces match the same subnet: eth0 eth1
dhcpd: Multiple interfaces match the same shared network: eth0 eth1
LPF/eth1/00:a0:d1:e2:f5:1f/192.168.3/24

dhcpd: Multiple interfaces match the same subnet: eth0 eth1
dhcpd: Sending on   LPF/eth1/00:a0:d1:e2:f5:1f/192.168.3/24
