PDF creation silently times out

PDF creation silently times out. xhtml Export works. I think it might me a folder permission issue. Can anybody tell me to which folder the html file is exported before prince starts the conversion? I want to check that html file needed for pdf creation is written to disk.

My folder structure is:

/home/basutato/www/pressbooks/wp-content/uploads/pressbooks/

Thank you for your help!

There is a known signals issue with Boehm GC when running on FreeBSD. The upcoming princexml release should fix this issue.

The latest version of princexml fixes the signals issue with FreeBSD Linux:
