duplicate ip problem

[Julie Xu]

Hi
 
my isc dhcpd has error:
Feb  7 09:01:50 myhost dhcpd: [ID 702911 daemon.error] uid lease 10.1.1.2  48 for client 00:22:4d:51:9a:00 is duplicate on 10.2.2.2/24
 
and the machine do get two IP addresses, both them can be pinged.
 
do I have anyway to stop the problem and save the IPs?
 
Any comments will be appreciated
 
Thanks in advance
 
xll
