Dennis,
Exactly the same configuration, give or take, as in the older post on this topic:
Michael Kitzmiller, "There is not enough free memory to load the entire file" #, 27 Jul 2007 5:23 am
That one had the same size of document as mine, which was under the RAM available.
My XP page file setting has 3 options: custom set to 1532 MB, system managed size, and a no paging file option. I used the first option, but moving this up to double doesn't help. The maximum is 4096 MB it appears.
Strange that FM knows right away upon starting the load that the file is too big. Almost as if there is some bad magic in the header that it uses to allocate or reserve memory with.
Also it looks like FM hits a peak memory usage during initial file load that is 6x of steady state usage. I have another file that I can load that is 10% smaller than the one that doesn't load, but this one hits the same peak usage. The peak usage happens right away and is the same for both files. This looks like a reserved memory that only gets used on commit.
It would be interesting to know if these limitations are from a design that is carried forward from old versions of FM, back when memory was more a premium. I last used FM to write a book more than 10 years ago, and made the mistake this time in trying to aggregate too much content into one file before splitting into the book/multiple document arrangement. I definitely won't make that mistake again.
