I'm using equation numbering in a book at section level. Somehow, after chapter 10, equation numbers turn 0 and remain that. I'm not doing anything special before that. Any clue?

Welcome to TeX.SE We're going to see a MWE including \documentclass and the appropriate packages to be able to diagnose the problem :) – cmhughes Nov 16 '12 at 19:39
In composing the MWE , start with \documentclass{<class>}, add the appropriate packages and preamble, and you can just make the first 10 chapters empty, and then add a formula to chapter 11 and show that the numbering is lost. If this does not reproduce the problem, add to it until it does. – Peter Grill Nov 16 '12 at 20:08
Without being able to reproduce the problem in the form of a MWE , it is going to be difficult to determine the source of the problem or suggest a fix. Personally, I have often solved my own problems in the process of reducing the amount of code actually required to reproduce the problem. – Peter Grill Nov 16 '12 at 20:09
With no MWE this is too localized. Request reopening if one is available. – Joseph Wright Nov 19 '12 at 8:45
