This looks like you ran out of memory on the host platform. There is an option for the System object to use an mmap flag that does not pre-allocate memory, but you still may run into issues. gem5 does not support simulating more guest memory than what is available on the host machine (i.e., gem5 has no swapping algorithm). This would be a good feature to add, though!
