Exporting Core Dumps
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
Optionally, you can export an SOS report with extra information about the system. For more information, see unresolvable-reference.html.
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.
