Looks like there is an issue with the DVA and PDFviewing with images - if you have an issue the response is....

"You can apply /PDFReturnNoImage in the gwdva.dva file and make all pdf conversion requests return no graphic images. If this stops the crash, we know the problem."

Im seeing this again
