[jira] [Commented] (PDFBOX-4525) PDF completely blow up the RAM on
RedHat
[ https://issues.apache.org/jira/browse/PDFBOX-4525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16825203#comment-16825203 ]
Tilman Hausherr commented on PDFBOX-4525:
-----------------------------------------
The PDF file has 6014 form xobjects. Each one of them is a transparency group with a colorspace. Creating this colorspace as a PD object does not use the resource cache, so it is created again each time.
I think this can be fixed, either by using a different way to check whether it is gray, or by passing the resources.

> 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
