John,
   Your XML application is set up to create a book from the single XML 
document? 1000+ pages is pretty big for one structured file. I suspect the 
problem is in the number of elements in that chapter rather than in the 
cross-references. You can confirm that theory by creating an XML document 
with just that chapter and importing it.
   If that is indeed the problem, you might try setting up the application 
to divide it into 4 or 5 book components. You may need to modify the DTD a 
bit to do so (easy to do with DocBook by changing parameter entities). I 
sometimes allow a chapter to have a structure such as:

<chapter>
    <chapterstart>...</chapterstart>
    <chapterpart>...</chapterpart>
    <chapterpart>...</chapterpart>
    <chapterpart>...</chapterpart>
       ...
</chapter>

where <chapterstart> has the chapter title, introductory paragraphs, and 
first sections and each <chapterpart> contains one or more sections 
(possibly preceded by paragraphs, lists, etc. if the <chapterstart> doesn't 
contain sections). Thus, the structure of <chapterstart> is just like a 
usual chapter, and that of <chapterpart> is the same without a title.
