[publican-list] ask help for "java.lang.OutOfMemoryError: GC overhead limit exceeded"

[dennisg]

Hi all,

I am a newer, and when I try to use publican to generate a huge pdf
document, I got the following exception:

......
warning: Line 1 of a paragraph overflows the available area by 25000mpt.

I have already try to add the jvm options in the ~/.foprc file
this is my .foprc file:
FOP_OPTS='-Xms200m -Xmx1024m -XX:-UseGCOverheadLimit'

But I still get this exception. And I wander what is the "Line 1 of a
paragraph overflows the available area by 25000mpt" means?

By the way, is it possible for publican to start from the chapter 3
rather than chapter 1? 
Because if I can not generate so big pdf file, I may try to generate
several small pdf files, and I don't want all these small pdf files
start from chapter 1.

Thanks for any suggestion!!!
