this is the post that has much of the same issue but my difference is that i am on Indesign 5.5.
To shed some more insight, I am trying to make a press quality PDF direct from Indesign.
I have 2 pages in my document, I was able to get one page PDFed buth the larger was not able to.
Why won't it PDF? What error is it showing? Do other presets work? What does your layout look like?
Have you tried removing elements one at a time and exporting it and seeing which element is causing the issue?
Have you got images on the page - perhaps resaving them to a different format and relinking them will help?
I sincerely doubt it's out of memory, seen as I work on a computer with 3gb RAM and a Intel Core 2 2.13ghz processor and I never get that issue.
Make a copy of your document. Delete half the itmes, then try to make a pdf. Keep repeating this process until you locate the exact object that is causing this. We can then better deteremine what the problem might be. Some common possibiliites:
Also try using another pdf preset to see if that works, like PDF X.
