This error occurs when an option/parameter cannot be parsed.
Probably there's something wrong when MRTG builds the parameter
string for the rateup call.

Just as an example: use of "%6lf" where " %5lf" would be better.
For small enough numbers there's no difference, for larger numbers
is does matter.  An example with 123, 1234, 12345 and 123456:

   printf("The number is%6lf in%4lf seconds\n");
   The number is   123 in 300 seconds  --> 7 words
   The number is  1234 in 300 seconds  --> 7 words
   The number is 12345 in 300 seconds  --> 7 words
   The number is123456 in 300 seconds  --> 6 words
If you're parsing the 4th token (in), it fails for the last line.  It
gets a number where it expects a word.  This *MAY* cause this error.

That is why I assume a (very) large integer causes this.

Modify the MRTG script so that it writes the rateup call to a log file.
This will most likely help you (and others!) to determine the cause.

You could also write your own rateup shell script that gets called by
MRTG, writes its arguments to a log file and calls the original rateup
program.
