Dear Ali, I know fop is very memory intensive but what you are saying is a memory leak. We also use fop to generate PDF reports using servlets inside tomcat. It is generating reports of size 20 pages with ease on a 256mb RAM machine with -Xmx set to 128m. It takes upto 90mb for generating a pdf of 25 pages. But when I generate it again it is releasing memory.
I doubt there is a leak in the driver code embedding FOP. Please check on it or if possible try to publish it. Somebody might help.
