Problem solved, thanks Sebastian , the problem was with swap memory, I had to change the fstab file and run swapon command in centos.

Eyeris Rodriguez Rueda Asunto: Re: Cannot run program "chmod" 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 Sebastian -------- Original Message -------- Subject: Cannot run program "chmod" Date: Wed, 30 May 2012 14:46:20 -0400 (CDT) From: Ing.
