It's been a while, but assuming that you are using Audible, Audible
manager used to have the option of subdividing large books into smaller
chunks which I found effectively addressed this problem.
This was back in PPC3 days, and, if memory serves, there was a serious
problem if the content was around 15megs, so that got me into the habit
of subdividing into 5meg segments.
