Reason:

  

This error is seen while installing WAS. "Not enough space" is related to swap space. If the RAM and swap space are low, This error would be displayed.

Solution: 

Check the swap space of the system currently using the command 

swap -s "This would provide the free swap space details"

To free the swap space, Check the processes utilizing more memory and kill the processes. This would increase the available memory.
