[jira] [Comment Edited] (PDFBOX-3284) Big Pdf parsing to text - Out
of memory
[ https://issues.apache.org/jira/browse/PDFBOX-3284?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15212079#comment-15212079 ]

First of all -Xmx768M isn't _that_ much memory. I'd recommend 1-2GB. I've parsed 100MB+ PDFs with PDFBox with this amount of memory. As Tilman says, often memory usage is due to how you're opening files, and sometimes its due to a particular PDF (e.g. a file which includes a single giant image).
Personally I've had the best results using a 32-bit JVM and opening the PDF directly from a File with no scratch file. Feel free to upload the problem PDF and we can see if there's something specific about that file which is causing the problem.

> Big Pdf parsing to text - Out of memory

> Key: PDFBOX-3284
> URL: https://issues.apache.org/jira/browse/PDFBOX-3284
> Project: PDFBox
> Issue Type: Bug
> Components: Parsing
> Affects Versions: 1.8.10, 1.8.11, 2.0.0, 2.1.0
> Reporter: Nicolas Daniels
>
> I'm trying to parse a quite big PDF (26MB) and transform it to text, however I'm facing a huge memory consumption leading to out of memory error. Running my test with -Xmx768M will always fail. I've to increase to 1500M to make it work.
> The resulting text is only 3MB so I don't understand why it is taking so much memory.
> I've tested this code over 1.8.10, 1.8.11 & 2.0.0 with same result.
> The pdf can be found [here|https://www2.swift.com/uhbonline/books/public/en_uk/clr_3_0_stdsmx_msg_def_rpt_sch/sr2015_mx_clearing_3dot0_mdr2_solution.pdf]
> My code:
> {code:title=Test.java|borderStyle=solid}
> @Test
> public void testParsePdf_Content_Memory() throws Exception {
> {
> InputStream inputStream = new FileInputStream("c:/tmp/sr2015_mx_clearing_3dot0_mdr2_solution.pdf");
> try {
> StringWriter writer = new StringWriter();
> FileWriter fileWriter = new FileWriter(new File("c:/tmp/test.txt"));
> PDFTextStripper pdfTextStripper = new PDFTextStripper();
> pdfTextStripper.writeText(PDDocument.load(inputStream), fileWriter);
> fileWriter.close();
> } finally {
> inputStream.close();
> }
> }
> {code}
