The exit status code '127' says something went wrong: stderr: "PROT_EXEC|PROT_WRITE failed.

Hi, I am generating PDF reports about the bundle knp_snappy, as it says in the title, so wkhtmltopdf command works perfectly in command mode but it does in the bundle, I get the following error:

The exit status code '127' says something went wrong:
stderr, "PROT_EXEC | PROT_WRITE failed.

I understand it is something related to permissions but do not know what I have to change to make it work.

my config.yml

knp_snappy:
    pdf:
        enabled:    true
        binary:     "/usr/bin/wkhtmltopdf"
        options:    []

My controller:

$html = $this->renderView('PanelBundle:Default:hotel-booking-summary.pdf.html.twig', array(
            'summary' => $summary,
            'agency' => $agency
        ));

        return new Response(
            $this->get('knp_snappy.pdf')->getOutputFromHtml($html),
            200,
            array(
                'Content-Type'          => 'application/pdf',
                'Content-Disposition'   => 'attachment; filename="file.pdf"'
            )
        );

I hope you can help me, greetings and thank you very much.

@JSGarcia I see that you have also opened an issue on SO
Please, also check if your server is RedHat-based. I'd bet that you have issues with SELinux kernel.

EDIT:
You can check SELinux with sestatus
If it is the case - please, check http://wiki.centos.org/HowTos/SELinux#head-faa96b3fdd922004cdb988c1989e56191c257c01 and http://serverfault.com/a/328867

Indeed it looks like permission issue with SELinux. I close due to inactivity.
