It looks to me that both errors are associated to memory, in the way that you do not have enough. Maya will take around 300Mb of RAM just to get going, once thats in it will start comsuming more and more and more until there is none left on your PC and it crashes...
Top tip my friend:
Use Low Res Textures to work with and switch them up to high res for the final render.
How much RAM do you currently have in your PC/laptop?
