intermittent channels saturated

[Figure-8]

My chart.vi intermittently shows all channels from one SCXI card saturated with a high frequency signal when I press the run arrow. If I just restart the vi, it sometimes cleans up and all channels look good. Ive checked connections, changes out PXI/SCXI chassis, 1125 SCXI card, pxi controller and pxiDAQ module with no luck. What would cause this?
