Problem Creating Postscript File with FrameMaker 7.2

My usual book easily goes more than 500 pages with lots of graphics (eps) and text. I am trying to create pdf. My problem is I am unable to print book in one shot - always received error messages. If I break the book and print selected files, I am able to create the postscript files. (I need to break into 5 to 6 postscripts files). But by doing this I lost the link to my TOC when I combine the files into 1 pdf file.

Have anyone encounter this problem before? Any suggestion? (I am using FrameMaker 7.2 and Distiller 6.0).
