Exporting Core Dumps

  1. To export the core dump for bug reporting purposes, specify the process ID and output file when you run the coredumpctl dump command:
    coredumpctl dump process-id -o output-file
  2. Optionally, you can export an SOS report with extra information about the system. For more information, see unresolvable-reference.html.
  3. On the same system or a different one, install the gdb package and then step through a core dump with the GNU Debugger by using the coredumpctl debug command:
    sudo dnf install gdb
    coredumpctl debug process-id

For more information about the coredumpctl command, see the coredumpctl(1) manual pages.
