To resolve the issue, the Linux Kernel of the SSFE server must be upgraded to version 3.8.0. Follow the procedure below on Appliance1 and Appliance2 if SSFE is deployed in a High-Availability setup.
  1. Log in to the SSFE server shell or command-line interface (CLI).
  2. Create a temporary directory to store the new kernel using the commands:
    # mkdir /tmp/new-kernel
    # cd /tmp/new-kernel
  3. Download the Linux image to upgrade the kernel using the command:
    # wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-lts-raring/linux-image-3.8.0-29-generic_3.8.0-29.42~precise1_amd64.deb
  4. After the file has been downloaded completely, verify the file checksum using the command:
    # sha1sum linux-image-3.8.0-29-generic_3.8.0-29.42~precise1_amd64.deb
    Make sure the value of sha1 is a0bfd9da477fc956600ea754c2124042ae62eea9.
  5. Install the kernel upgrade by running the command:
    # sudo dpkg -i linux-image-3.8.0-29-generic_3.8.0-29.42~precise1_amd64.deb
  6. Once the upgrade process is done, reboot the server by running the command:
    # sudo reboot
  7. After the reboot, verify that the kernel has been upgraded to 3.8.0 using the command:
    # uname –a
