I don't know V8. But it seems that you want to allocate about 1 GB (1000 * 1024 * 1024) GB of physical memory and this amount is not available. This may be due to an internal V8 limit (a quick research found the --max-old-space-size command line flag) or your system has not enough remaining free physical memory.
