No, no change to the OS. I appreciate your help in getting this far with this though. Thank you!

Alright, I tried with 1, 2, 3, and four threads (using convert -limit thread 1 ..., convert -limit thread 2 ..., etc.) and the only one without the black bars is the one with the single thread. ??? Any idea why would it not be able to handle more threads, like it has in the past?

Woah! I think you may have hit on something here. When I run it with convert -limit thread 1 ... there are no black bars! This has never been a problem before, and I am concerned that it will impact the speed in which I can process the files, but it's a start! However, I have no idea where to go fro...

You have 24 processors and OpenMP enabled. Another thing you could try is to disable Openmp or try using one thread. convert -limit thread 1 ... Woah! I think you may have hit on something here.

snibgo has a good idea. Try converting to PNG without the rotate. Does that work? Then try converting the PNG to JPG. Does that work? If both converts work, then put in the rotate again and see if those work. Alright, so the results were: Converting to PNG without the rotate -> works, looks good wi...

It's a question of pinning down where the problem lies. It could be reading the input, doing the processing, or writing the output. If it happens for all input and output file types, then the problem is probably in the processing (eg a memory issue). But the problem may be restricted to JPG formats...

Thank you for the suggestions. The files are jpg images and the output is jpg. The results for convert -list resource are: Resource limits: Width: 214.7MP Height: 214.7MP Area: 64.317GP Memory: 29.95GiB Map: 59.899GiB Disk: unlimited File: 18750 Thread: 24 Throttle: 0 Time: unlimited I'm not sure wh...

Oh, and this same thing has happened to hundreds of images that it has been tested on. The black bars always appear in the same place too, regardless of the image.

I just moved from/to the following: ImageMagick-nox11: 6.9.2.3,1 -> 6.9.4.3,1 pecl-imagick: 3.1.2_2 -> 3.4.1 Full version info: Version: ImageMagick 6.9.4-3 Q16 amd64 2016-05-24 http://www.imagemagick.org Copyright: Copyright (C) 1999-2016 ImageMagick Studio LLC License: http://www.imagemagick.org/s...

Yes. For example (using HTTP): convert http://snibgo.com/imforums/rgimage1.png r.png This succeeds. But if I insert ... <policy domain="coder" rights="none" pattern="HTTP" /> ... into policy.xml, the command fails with: convert.exe: not authorized `//snibgo.com/imforum...

ImageMagick coders are the modules that read and write formats that are identified by letters before a colon at the start of filenames. For example: convert PNG:in.png PNG32:out.png convert http://my.domain.com/in.png out.png Coders that are internal to IM (as opposed to external delegates) have so...

So with the new vulnerability that was announce today (see here: https://www.imagemagick.org/discourse-server/viewtopic.php?f=4&t=29588), the solution is to add a set of lines to your policy.xml file. The lines that were mentioned include the following: <policy domain="coder" rights=&q...

This was actually already announced in this forum as well, here: https://www.imagemagick.org/discourse-s ... =4&t=29588

Can you explain a little more about what these policies will do? For example, we currently access all of our imagemagick processes through HTTPS calls; would including HTTPS in our policy file like this cause issues with that? (Sorry for my ignorance!) Edit: On second thought, if HTTPS is a coder it...

Great! Thanks for the additional information. It is interesting to me that they decided to make such a large change to the way they handle the images. I have a feeling that quite a few people are going to be having these same issues in the coming years as they update their IM installation.
