This is not really a problem of Nutch. The fork to run the command "chmod" failed because your machine does not have enough memory (RAM + swap).
For more information you should google for error=12, Cannot allocate memory hadoop error=12
Possible solutions (assuming you are using Linux):
look for how to "overcommit memory"
increase the swap space
