Preview and renditions are not getting created on image upload in DAM

[joe_s66]

After we upload images into the DAM on our AEM production author (version 6.4.8)  the preview for the image doesn't work and in CRXDE the metadata, renditions and related nodes don't appear under jcr:content for the image.  (it does work in our lower AEM environments) Here's the error message:
