Hi Gary -

I really could not say. The philosophy of Perl is 'no artificial 
limits', so the size of the number should not be an issue unless 
something in the mrtg code itself chokes on it. I know that earlier 
versions could not graph traffic stats over 100Mbps because I had to 
upgrade due to that limitation.

Have you tried turning on debug modes in mrtg and running to to see 
what's going on internally?
