When you create a new partition like space (Swap) and get an error like memory exhausted by input buffer of size 1073741824 bytes,
 

root@thelinuxfaq:~#   sudo dd if=/dev/zero of=/swapfile bs=1G count=2
dd: memory exhausted by input buffer of size 1073741824 bytes (1.0 GiB)


You can give bc=1M instead of bs=1G.
