Thanks for everyone's help with tracking this down.  I was not aware that
rrdtool only used integers for COUNTER- I didn't/don't see that on the
rrdcreate man page.

As I mentioned, this is done via PHP- which doesn't have a "long long" type
AFAIK- large integers are stored as floats.  I should be able to format the
output in some way that makes it appear as an integer though, which should
fix this problem.

Thanks again!
