[mrtg] Possible MaxInt problem in mrtg 2.9.10 ?

[Soffen, Matthew]

I'm using a script that is working fine (manually verified) but it "seems"
like mrtg, when attempting to store this,   is hitting some sort of max
value limit.

I'm tracking bytes transferred from the web server and it is storing this in
the .log file

985186049 3796641792 3796641792
985186049 2131017728 2131017728 2131017728 2131017728
985186024 2131017728 2131017728 2131017728 2131017728
985185900 2131017728 2131017728 2131017728 2131017728

Its storing only the 2131017728 value.  I didn't see anything list
indicating any Max Int limits.  And this isn't a value that makes sense.  Is
there some limit of 2147483647 (7FFFFFFF) in the code - some integer that's
too small ?  If this is inherent (and not changeable) then I'll can just
convert to Kbytes instead of Bytes.

And if it is a "known" problem, maybe this can get added into the FAQ ?

Thanks.
