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.
Regards,
Srinivas.

Dear Thomas
Here is what happens. I have closely watched the
memory usage of FOP:
I have a report with around 17 pages. One table with
12 columns. I use
Velocity to put the data inside the FOP template.
When it starts
rendering the report (PDF or print preview) it
consumes 50 MB. Second
run another 50MB, third run another 50 MB , then
with 256 MB RAM , when
I go for forth run, CRASH BOOM BANG! Out of memeory
exception.
My users usually use the report during the day ( 7
hours) 10 to 20
times. So even 512 MB RAM workstations get out of
memory easily.
Running it under another JVM is a good idea but as
you know it is not
feasible from performance point of view.

Does this happen with the first report after
starting the Java VM or
later on (after some reports have rendered
correctly)?
Perhaps you may start FOP in a separate VM and exit
it after the report
has done, that's not ideal for performance but for
stability.

To all FOP developers
The out of memory problem of FOP is getting critical
for our company .
So this is an offer for a FOP developer who can fix
this problem. If
anyone of you can fix this problem please contact me
and we can talk
about the offer. We are open for the price.
