Rogue DHCP service from Arduino Yun

My Wifi system (Ubiquiti Unifi) is periodically (pretty much at random maybe once or twice a day) reports my Arduino Yun as a rogue DHCP server. The Yun is connected to the wifi network as a wireless client with a static IP, but I'm guessing its capability of being a DHCP server is periodically triggering for some reason.

Has anyone else seen this and know a fix?

Has it been updated to the latest release ? What is the sketch that is running ?

Do you have any more information about your set up ?
