I'm no expert in this, but what's your exact memory amount you've tried? I'm using CATALINA_OPTS=-Xmx384M and that works fine with me, although my pdf documents aren't that big. I also had a small problem that the tomcat that I installed: it created a shortcut in my program files that did not start with the correct parameters, you do need to start with the startup.bat /sh in the bin directory to have that memory parameter in use.
I also switched to running my pdf stuff in a thread because fop takes a lot of time. When the xml doc is ready I call a thread in my flow that handles the fop part while I send the user a page that tells him his request is handled and that a link will appear on some page when the pdf is ready. This may give some ideas, because you're mentioning the twenty minute waiting period.
