Out of Memory problem
I have seen type of bug mentioned on the web, here is a link I found
basically describing a problem I appear to be having.
http://www.owal.co.uk:8090/asf/servlet/asf/screen/DisplayQuestionAnswer/acti
on/SetAll/project_id/18/faq_id/276/topic_id/495/question_id/788
I have ran into this with large images and have avoided those for now, but I
also have seen this problem in the following one column, one row, table,
that I have included. I am converting html to pdf on the fly on our server
using FOP, but the below is a scaled down portion of one document that will
get into an endless loop. I am using version 17, but am seeing the
following locally using 18, also. I have notice other tables will carry
over to the following page, but this appears to try to fit on one page and
when it can't it appears to look for a page that it can fit on.
Example. (Reducing margin-top and margin-bottom will allow this to
successfully convert, but have it set this way to show the problem I am
seeing)

meetings of 18 top advisors, women account for eight of those in attendance.
The president has more women in top, traditionally male-dominated
White House positions than any other president. Furthermore, aide Karen
Hughes is the highest-ranking female aide to any modern president. But that
shouldn't be surprising, as an analysis of Bureau of
Labor Statistics data for 2000 from the Employment Policy Foundation finds
that women are entering other male-dominated fields at increasing rates, and
that those women now earn the same or more
than their male counterparts. EPF identified the top 10 occupations where
women's participation has increased most since 1989:</fo:block>

Hooray ! Someone using the FAQ. I have a warm glow inside.
Folks - Please remember to mark an answer as for the FAQ
or preferably email it to me if you think I should add it to the FAQ.
(The same goes for any of the Apache FAQs on the main Apache site)
I don't have any good news regarding this I am afraid - I have seen very similar
problems and don't have a solution.
FOP doesn't seem to be able to split the table cell over two pages...
Don't know why.
Alex
