-----------------------------------------
Please include your version number. And do you close your PDDocument object? It
would be useful to include a minimal servlet as well.

> Project: PDFBox
> Issue Type: Bug
> Reporter: Ankit Khanal
>
> I am running with 6GB of heap space and running PDF to PNG conversion in a
> servlet container(tomcat). This happens only when running thousands of
> requests for conversion.
> JVM memory statistics shows heap space never going above 1GB and non-heap
> memory is also constant but the linux process or windows process seems to
> consume around 8GB of memory.
> Heap dump shows that the largest object is sun.java2d.Disposer and is around
> 200MB.
> It seems that the leaked memory is native memory used by java2d and not
> accounted in the heap memory statistic but this growth of sun.java2d.Disposer
> memory is proportional to the growth of process memory(linux 'top' command).
