NaN means not-a-number, which is a floating-point code defined by the IEEE 754 standard (which most FPU's in commodity PC's adhere to). It is generally produced by arithmetic operations that produce invalid results, such as division by zero. I think by rrdtool is programmed to ignore FPU exceptions and so produces these codes whenever such things occur. Check the operations rrdtool performs and see if your data can induce a division by zero (most common) or some other type of FPU error. -- Rafael R.
