This log message means that the signals coming out of this AP were being interfered. Do you have any sources of interference near the AP like Microwave ovens, cordless phones, Bluetooth devices, florescent lights? Please ensure that the AP is far away from all these sources of interference.

I'll suggest opening a case with Ruckus Support for this.
