So, you're saying it is taking longer BUT it still eventually shuts down, right? I don't know of any specific reason why it would be slower than 32 bit. Have you checked the alert log and dump directories to see if there are any errors occurring that you need to review? I'd suggest you check that out and if it continues to be a problem or doesn't shut down at all, contact Oracle support directly.
