I have looked around for this answer and found a few good articles on how memory is managed, dpi vs resolution, and so on. I have seen some posts where people are trying to edit "high resolution images" but nothing near the size of what I am trying to do. I have 38400 x 21600 resolution, 11 layer, .pdn, which Paint.net is the only application where I have been able to successfully edit. Which is feat in of its own I think as GIMP and Photoshop just crash once the image is opened or can't open it due to lack of memory.
I do occasionally get some crashes in Paint.net but that's when I use some add-ons or resizing. I think the reason why is that this image is taking 28 gig of the 32 gig I have in this system. The application is trying to find a contiguous block of memory and attempts to write in a system reserved section of RAM.

Exception details: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
I saw the post where it states the memory requirements for images is "(W x H x 4) x (L + 2)" so I know the simple solution would be to reduce the number of layers (or get more RAM). The number of layers can go from 7 to 11 layers as I work with the image so that's not out of the question.
TL;DR - What I am wondering is if there is anything I can do to help not only avoid crashes but improve the performance of Paint.net for an image this size.
