For anybody who may ever run into this problem, I solved it by setting the rendermode to "direct". I had it set on "gpu", which improved the performance of my application tremendously, especially when scrolling lists that contained images. It made it very smooth and I wish that I could continue to keep the rendermode set to "gpu". Sadly, that is what was causing my app to lock up or crash. As soon as I changed this back to "direct", Adobe's recommended setting for mobile, I ran the app for over an hour with not a single hangup or crash.
