One of the last things I added to the m1 pdf plugin was an option to move the
table of contents to the end of the pdf. This removes the page-number forward
references and solved some reported memory problems, see
http://jira.codehaus.org/browse/MPPDF-62.
So if this is an option for you, you can try to move the TOC to the end of the
pdf, or skip it entirely.

Hi Kent,
I do not know the current incarnation of the plugin but worked with
DocBook before - the transformation takes a lot of memory since it
requires the PDF to be generated completely in-memory to resolve all the
page numbers and cross-references. I think with M1 it took more than 1GB
to generate th O'Reily SVN book ...
Cheers,

It only occurs when I build the docbook pdf files, anyone know why this
happens?
Also, it does go away if I increase the heap space to 1,5 Mb, but that is
hard to change in all environments etc...
