I am using Moodle 2.4.4, and installed PDF submission plugin (version 2013013000). Recently, we found that a ghostscript job keep running in the server. We checked and the ghostscript job seems trying the process PDF files, which contains unsupported image format (eg. JPEG2000).
We plan to upgrade the ghostscript to 9.06, hoping to solve the problem. Please give some opinion whether ghostscript 9.06 is stable for Moodle 2.4.4 or higher version?
