I think you hit the nail on the head...I copied the script onto one of
my customers VMs and it ran fine.

Well fine is relitive. It runs now but the output on the graphs (and the
numbers below) are all 0.

I didn't imply that you should remove that newline.  I think it is
better to keep it in.  I was just wondering why the output did have
a newline but your code did not show this.

In this case I have only one suggestion left, if that doesn't work
then someone else will have to step in:

What version of mrtg are you using, maybe you should upgrade or, if
you use the latest version, try one version below.

good luck with your problem.
