Gitlab Runner Failure - " The scheduler failed to assign job to the runner, please try again or contact system administrator "

  • Self-managed

  • Gitrunner Version - 16.11.0
  • Executor - docker

I am getting " The scheduler failed to assign job to the runner, please try again or contact system administrator " error all of a sudden . Pipelines were working normally. Its affecting all existing projects as well as the newly created. I am using the default gitlab-ci.yml for testing .

stages: # List of stages for jobs, and their order of execution

  • build
  • test
  • deploy

build-job: # This job runs in the build stage, which runs first.
stage: build
script:
- echo “Compiling the code…”
- echo “Compile complete.”

unit-test-job: # This job runs in the test stage.
stage: test # It only starts when the job in the build stage completes successfully.
script:
- echo “Running unit tests… This will take about 60 seconds.”
- sleep 60
- echo “Code coverage is 90%”

lint-test-job: # This job also runs in the test stage.
stage: test # It can run at the same time as unit-test-job (in parallel).
script:
- echo “Linting code… This will take about 10 seconds.”
- sleep 10
- echo “No lint issues found.”

deploy-job: # This job runs in the deploy stage.
stage: deploy # It only runs when both jobs in the test stage complete successfully.
environment: production
script:
- echo “Deploying application…”
- echo “Application successfully deployed.”

Can anyone help please …
