[rrd-developers] errors using embedded rrdtool

[D.Walsh]

I've created a mail stats app, I've been deploying it in different 
environment, seems a problem exists only with the PHP embedded rrdtool, 
I use the following information (hardcoded) as a test and only 
experience a problem when rrdtool is embedded in PHP, any ideas on the 
cause/solution?
Here are the arrays and the resulting errors which only occurs with the 
embedded rrdtool.

On a separate issue I've rewritten the info routine for PHP to be more 
descriptive to include important/relevant information.
(this is not used on any of the machines currently being tested for the 
embeded rrdtool so it is not a consideration or a contributor to the 
problem)
