Find out what part of your site generates PDF files, as they said in other answers it's part of the Dompdf php library.

You could use a shell script to clear your tmp folder and set a cron job to run as often as you'd like

#!/bin/bash
rm -rf /tmp/*
rm -rf/var/tmp/*
fsck -A
exit

Dompdf is a html to PDF converter, it has a PHP rendering engine and reads in external style sheets.

The project lives at code.google.com/p/dompdf/ I'm sure they have a support channel that might be able to help get the cleanup correct.

Seems to be related to the dompdf library. Since you seem unaware it's even on your site, it's probably being used as a library by some utility or plugin for a CMS, for example. Does your site offer a feature to download a given page as a PDF? That would be the first place to look.
