Why the version in "release" is > release: 3.10.0-693.17.1.el7.x86_64 ? > Looks like it. Not only was the vmcore created from the crash of a rhel7-vintage kernel (3.10.0-693.17.1.el7), the dumpfile also shows that kdump operation failed to complete correctly, as indicated by the DUMP_HEADER_INCOMPLETED flag. That flag would have been removed if the dumpfile creation completed normally.
