It looks like kdump might not be enabled in your kernel settings, or might not have sufficient memory to run. You'd need to follow this guide to use system-config-kdump or edit your Grub file and configure reserved memory for kdump to use. This resource has a step-by-step guide for installing dependencies and configuring settings.
