---------------------------------------------------
Thanks a lot, [~tilman] This is useful. Appreciate it.
> OOM issue in using PDFBOX
> -------------------------
>
> Key: PDFBOX-4876
> URL: https://issues.apache.org/jira/browse/PDFBOX-4876
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 2.0.19
> Reporter: Dushyanth Balasubramanian
> Priority: Major
>
> I see a lot of OOM for many documents which are either big in size or have
> many objects per page or complex images. We started the project with JVM size
> of 4GB and now we have increased it to 24GB JVM memory. The OOM issues have
> reduced but we still see some OOM issues. We have followed all the
> recommendations given here:
> [https://pdfbox.apache.org/2.0/faq.html]
>
> Here is the stack trace. Any recommendations for preventing OOM? Thanks.
