When I try to typeset a book I’m writing however, it gets stuck on chapter 2. The strange thing is that I haven’t touched chapter 2 in months. Here’s the relevant (I think) part of the console log:

Howdy,

This could be caused by one of several things but I'd first guess an infinite loop of some sort. Without some more information this is very difficult to diagnose. You might try using the etex package (\usepackage{etex}) but i'm not at all sure that will help.

Good Luck,
