Circleci break when use checkout 2

When my build step is in Checkout, break the build e return the error in image bellow. This error did not happen two days ago. And config.yml was not changed. This error has blocking we production deploy.

Error description:

Either git or ssh (required by git to clone through SSH) is not installed in the image. Falling back to CircleCI’s native git client but the behavior may be different from official git. If this is an issue, please use an image that has official git and ssh installed.
Cloning git repository
Enumerating objects: 113762, done.

Description 2:

CircleCI was unable to execute the job to completion, because the CircleCI runner received a kill signal midway through the job.

This means that that either the agent got killed accidentally (through a killall command), or that the build container entrypoint (i.e. PID 1) allocated too much memory or terminated early. Consider clearing entrypoint/command values and try again.

Hi @SergioOviedo. Welcome to the CircleCI community!

What image are you using?
