Bitbucket failes due to memmory failed on self hosted agent

Finally i have it done with few options and using own self-hoster runner:

                    variables:
                        SONAR_SCANNER_OPTS: "-Xmx3062m"

    services:
        docker:
            memory: 8192
        docker-sonar:
            type: docker
            memory: 6144

I know that file is big, but in my opinion it might take more time but should not fail.
