Overflow error question

When doing FOP, I get

WARNING: Line 1 of a paragraph overflows the available area by 12000mpt.

What is "mpt"?

It's happening in a code example with a line length that is not terribly 
long. A snip of the XML follows but my question is, how to avoid these 
errors? In some documents the errors take up pages and pages.
