Conversion problem with 0.9.2, one book

[tomcooke]

I am using 0.9.2. no option changes, I am converting the book "Apologetics Study Bible, The.azw3"
which is about 9000 pages. I have converted 29 other books with this version so I think its something with this book, It gets to 47% and then I get this error:

I suspect that this is just too big. You ran out of RAM (or the number got too big for your OS)

Yes that is the error. I really want to know what causes the out of memory error. The conversion hits 47% after just ten minutes and stays there (probably in a software loop) till the out of memory error occurs 200 minutes later. This is not the first large book that i converted but is one of the few that fails.
