Docker jobs fail with exit code 137
Overview
As we see in gitlab-com/gl-infra/production#4916 (closed) when we deployed v14.0.0-rc1 to GitLab.com shared runner fleet we are seeing jobs randomly failing with exit code 137. In gitlab-com/gl-infra/production#4916 (comment 605537326) we confirmed that it's not an infrastructure issue but some regression from 14.0 release.
There already have been investigations done on the application level in gitlab-com/gl-infra/production#4916 (comment 604723523) to investigate what can be the change.
