      AIDA disc statistics indicate that fast discriminators were source of higher rate - next time this 
      happens we should check HitRate to see whether this is a specific channel or channels and possibly 
      mask

      nnrpi1 is offline - we suspect wrench or power tool placed too close to RPi when we moved AIDA
      into DTAS and we jostled one or other of the cables connected to nnrpi1
