This will be hard to debug as the generation of this series of PDFs
takes almost an hour and the exception happens late in the process. But
I will test if the exception does not happen when calling
fopFactory.getImageFactory().clearCaches() manually.

The image cache has been improved so the manual image cache clearing

Still, you can call fopFactory.getImageFactory().clearCaches(). But if
this is really necessary then we have a problem in the image cache that
should be solved and not worked around. I have done tests a few months
ago and did not manage to cause OutOfMemoryErrors. So if your
environment does, it would be great if you could try to debug and find
out why exactly this happens. The image cache uses a WeakHashMap for the
images so the memory should actually be reclaimed if the JVM starts to run
out of memory. So if that doesn't happen, something is wrong.

We have a strange behaviour in our application. There is the possibility
to generate single PDFs or several PDFs in series. There is no problem
when producing single PDFs but when generating large series of PDFs (the
same as can be generated singly), we ar running in an
OutOfMemoryException. As is stated on the "FOP Memory" webpage, clearing
the image from time to time cache might prevent memory exhaustion (we
are running FOP embedded). Do you agree that this could solve the problem?
How to do this with FOP 0.92beta? The description is only available on
the webpage for FOP 0.20.5...
