Dear Alan and Alain, We have had some memory issues lately, which we are working on. It hadn't occurred to me that they could be connected. Thanks very much for your responses!

Please do not click links or open attachments unless you recognize the source of this email and know that the content is safe. ******************************************************************************************************************************************************************************************* Dear Helen, I downloaded one of the PDFs in the linked collection and was able to create a nice thumbnail using ImageMagick directly on the command line: $ convert -flatten CUCSSN83100009.pdf\[0\] CUCSSN83100009.pdf.jpg $ convert -thumbnail x600 CUCSSN83100009.pdf.jpg CUCSSN83100009-thumbnail.pdf.jpg So the PDFs seem OK. It could be an issue with memory or ImageMagick version/configuration on your server. Try running the dspace filter-media command in verbose mode for one of the PDFs to see if there are any errors: $ dspace filter-media -i 10976/167371 -f -v Regards, On Thu, Jun 11, 2020 at 12:15 AM Baer,Helen <[email protected]<mailto:[email protected]>> wrote: Hi everyone, One of our partner libraries has a recurring problem with blank thumbnails for pdf's. Their process is to create the original PDF from separate TIFFs in Adobe, then use Adobe Acrobat Pro 2017 to make a smaller sized file. Have any of you seen this before? We're thinking the problem is with the source content, not DSpace, but I thought I'd ask around and see if anyone has a solution.
