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

> Key: PDFBOX-2688
> URL: https://issues.apache.org/jira/browse/PDFBOX-2688
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 1.8.8
> 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).
> {code}
> BufferedImage image = null;
> ByteArrayInputStream pdfStream = getpdfbytesfromExistingDoc();
> PDDocument document = null;
> PDPage page = null;
> COSDocument cosDoc = null;
> PDFParser parser = null;
> try {
> parser = new PDFParser(pdfStream);
> parser.parse();
> cosDoc = parser.getDocument();
> document = new PDDocument(cosDoc);
> @SuppressWarnings("unchecked")
> List<PDPage> pages =
> document.getDocumentCatalog().getAllPages();
> page = pages.get(0);
> int imageType = BufferedImage.TYPE_INT_ARGB;
> image = page.convertToImage(imageType, 72);
> } finally {
> if (cosDoc != null) {
> cosDoc.close();
> }
> if (parser != null) {
> parser.clearResources();
> }
> if (document != null) {
> if (page != null) {
> page.clear();
> }
> document.close();
> }
> }
> return image;
