What is strange is that I've tested the 2.0.9 with the patch (4392) on RedHat,
and it took only ~700Mo.

> Project: PDFBox
> Issue Type: Bug
> Components: Rendering
> Affects Versions: 2.0.9, 2.0.15
> Reporter: lienhardt
> Assignee: Tilman Hausherr
> Priority: Major
> Labels: optimization
> Fix For: 2.0.16, 3.0.0 PDFBox
>
> Attachments: crash_redhat.pdf, testPdfBox.jar
>
>
> We received a PDF that has completly killed the Tomcat on a production
> application.
> The symptoms are the same as PDFBOX-4392, but the PDF file is different.

> ensureDisplayProfile
> AVERTISSEMENT: ICC profile is Perceptual, ignoring, treating as Display class
> {code}
> We test it on RedHat5 VM in develop and reproduce it with a sample test
> program that read the PDF, and create a small image. The program is looping
> and after the 4th reading it took 20Gb of memory and was killed by the OS to
> prevent the crash of the computer.
> I've tried with version 2.0.15 and the problem still be the same.
> We can test it with java -jar testPdfBox.jar crash_redhat.pdf
