I've been having this issue for quite a while now but it seams to get worse and worse the more time passes. I'll be working on a document in Photoshop, nothing too crazy, when all of the sudden I'll get an error message saying "Adobe Photoshop has to close"(I can't remember the exact wording of the error message but that's essentially it.) This seams to happen a several times a week. The Document Size I was working on was 11"x 34" at 300 resolution and it did have a few dozen layers in it. This issue has been happening on multiple versions of CC and will even happen in other Adobe Programs like AE and Premier Pro.
I'm using a Win 7 64bit machine with 16 GB Ram and an Intel i7 and Photoshop CC 2015
