After uploading certain PDFs, the AEM instance crashes. In the log files, you see OutOfMemoryError. In thread dumps, you see threads like the one below showing threads stuck in the JVM code sun.java2d.cmm.lcms.LCMS.createNativeTransform:

If you are using Oracle JVM on Windows or Mac, configure Java to use the legacy KCMS API instead of LCMS. There is a known issue that makes this fail to work in JDK8 on Linux.
Modify your AEM start script and add this JVM parameter to the CQ_JVM_OPTS variable:
-Dsun.java2d.cmm=sun.java2d.cmm.kcms.KcmsServiceProvider
# default JVM options
if [ -z "$CQ_JVM_OPTS" ]; then
CQ_JVM_OPTS='-server -Xmx1024m -XX:MaxPermSize=256M -Djava.awt.headless=true -Dsun.java2d.cmm=sun.java2d.cmm.kcms.KcmsServiceProvider'

- Go to http://host:port/crx/de/index.jsp and log in as admin user.
- Browse to this path where {slingid} is the sling id of the AEM instance
/var/eventing/jobs/assigned/{slingid}/com.adobe.granite.workflow.job.etc.workflow.models.dam.update_asset.jcr_content.model - Right click and delete the node com.adobe.granite.workflow.job.etc.workflow.models.dam.update_asset.jcr_content.model
- Save.
- Restart AEM.
This deletes all the active sling jobs for PDFs that are crashing AEM.

Run this command in that folder to make sure that the rasterizer works (replace pdffilename.pdf with the filename of the PDF document).
/opt/aem/author62/rasterizer/PDFRasterizer -d -p 1 -s 1280 -t PNG -i pdffilename.pdf
Total time in image conversion (in ms): 163 Total time (in ms): 896. Time to initialize: 12. Time for conversion: 884
-
Assuming the rasterizer works OK on the command line, follow the steps in this article to configure it to work in AEM.
