Currently, our docker images, and many development/QA computers are not creating coredump files when witness software crashes.

We need to investigate why is that. We need clear and accurate instructions on how to enable coredump file creation on software crash, and enable it in all our docker images (peerplays and qa environment).

Coredump generation and access is enabled by installing systemd-coredump package in Ubuntu. This package is installed in both Peerplays docker images and QA environment.

Coredumps can be accessed with following command

coredumpctl

Which will produce output similar to this
