25.6. System is displaying signal 11 errors

A signal 11 error, commonly known as a segmentation fault, means that a program accessed a memory location that it was not assigned. A signal 11 error can occur due to a bug in one of the software programs that are installed, or faulty hardware. If you receive a signal 11 error during the installation process, verify that you are using the most recent installation images and prompt the installation program to verify them to ensure they are not corrupt.

For more information, see Verifying Boot media.

Faulty installation media (such as an improperly burned or scratched optical disk) are a common cause of signal 11 errors. Verify the integrity of the installation media before every installation. For information about obtaining the most recent installation media, refer to the Product Downloads page.

To perform a media check before the installation starts, append the rd.live.check boot option at the boot menu. If you performed a media check without any errors and you still have issues with segmentation faults, it usually indicates that your system encountered a hardware error. In this scenario, the problem is most likely in the system’s memory (RAM). This can be a problem even if you previously used a different operating system on the same computer without any errors.

Other possible causes are beyond this document’s scope. Consult your hardware manufacturer’s documentation and also see the Red Hat Hardware Compatibility List, available online at https://access.redhat.com/ecosystem/search/#/category/Server.
