This here is what I would guess is the most likely answer. Look at the build configuration and explicitly make everything build x64. There may exist scenarios where you would have to explicitly build x86, but explicit x64 is what's generally been the golden hammer for these things in my life. It's not truly "out of memory". It's just confused. Would lean toward this being near certainty if you hit it right upon app start or possibly the first shot at some specific app action.
