You don't have enough virtual memory on your machine to support that much simulated physical memory. There are two causes: 1) You're on a 32-bit OS and you just don't have the virtual address space available. There's nothing you can do here. 2) You don't have enough RAM + SWAP to cover the amount of physical memory you want to support. You can add a swap partition or file and that will solve your problem.
