If I'm reading things correctly, the pmwiki2pdf recipe relies on an
HTML to PDF converter that has been written in PHP.  Since the converter
is written in PHP, I suspect that converting large HTML pages (2 MB)
to PDF would end up taking an absolutely huge amount of memory.  

If you're primarily wanting to convert wiki pages to PDF, I'd recommend 
looking at the GeneratePDF or WikiPublisher recipes, as they use C-based
utilities for their conversion, which will likely be a lot faster
and use up much less memory.

If you're just wanting to have a way of storing static pages for
retrieval, you might look at the ExportHTML recipe.

When you changed /etc/php.ini, did you also restart the webserver?
Did the "Fatal error..." message indicate a larger allowed memory
size (i.e., 1GB instead of 32MB)?

But no matter how we look at it, 1GB is an awful lot of memory for a
PHP script to be using, and I'd suspect that something is seriously amiss
somewhere.

PmWiki itself doesn't come with or use anything called 'pub/js', so I'm
guessing it must be coming from a recipe or skin.

Hope this helps,
