Our C/A instance is nearly ready to launch but we've been experiencing a lot issues with uploading media if it's any larger than a few KB (such as PDFs or quality JPEGs). Currently we are using Imagick.
Initially, we were getting a timeout or CSRF token error when uploading media. I had our IT team fix that error.
However, instead of getting the error CA will say "Image saved" but nothing will have happened. Batch imports initially start but eventually choke and stop. We followed guidance and suggestions from other support threads to change the tmp folders, etc. but we're still experiencing the same issues with the added issue that batch imports will not even begin despite the tmp folders filling up with large amounts of data (32GB). Using the UI to upload media results in "image saved" albeit with no media.
We were using Gmagick/Graphicsmagick priorm which had it's own issues. Namely files will are only recognized as binary and display the document placeholder icon instead of a thumbnail/media. So the thought of falling back to this (since it seems to be the preferred processor) present just as many issues.
Unfortunately, due to the pandemic I was laid off and I've only been granted a week or two to come back and try and get this project wrapped up. Any help or suggestions would be greatly appreciated.
