Gitlab: There has been a runner system failure

I use Gitlab for doing Continuous Integration and Development and all of a sudden I get this error message "There has been a runner system failure, please try again"

enter image description here

There's no real error message or error code.

I've tried restarting the gitlab runner, using gitlab-runner restart, I've done a reboot of the server its running on but I keep getting this error message on Gitlab whenever I push a code change.

In my case I got this error

WARNING: after_script failed, but job will continue unaffected: Error response from daemon: error creating overlay mount to /var/lib/docker/overlay2/53675a50d5dd838707b97d7ab37f3ace6bcf80f2ac9d80171f7fe9f996bb7d8d/merged: invalid argument (exec.go:78:0s)  job=22255 project=7 runner=h8gbgAAh

systemctl status docker.service showed that the service failed
sudo systemctl restart docker gave "Job for docker.service failed because the control process exited with error code"
sudo dockerd --debug as suggested, but not sure if it helped
=> sudo reboot brought everything back on tracks.

After a couple of hours, I realized the issue is that the server that Gitlab Runner is running on has no space left.

I logged into the server in question. Looked at the Gitlab log file using the following command: journalctl -u gitlab-runner

And it showed me the following logs:

May 21 08:20:41 gitlab-runner[18936]: Checking for jobs... received                       job=178911 repo_url=https://.......git runner=f540b942
May 21 08:20:41 gitlab-runner-01 gitlab-runner[18936]: WARNING: Failed to process runner                   builds=0 error=open /tmp/trace543210445: no space left on device executor=docker runner=f540b942

To fix this issue I ran the docker container prune command which clears out stopped containers.

Alternatively you could use the docker system prune command which would remove all unused objects.

See https://linuxize.com/post/how-to-remove-docker-images-containers-volumes-and-networks/ for more information about those docker commands.

Afterwards, I no longer got the error on Gitlab when pushing changes.
