Hi

 There´s not much to say besides the clear information on the log:  IP Conflict.  Furthermore, you need to figure out to who the mac address belong.

Do we observe connectivity issues or it's just an wlc msglog that appear false-positive.
are multiple dhcp servers with overlapping scopes used.
what's the arp timeout config on wlc - was it changed from default.
