Occasionally jobs are stuck in "waiting for a runnner to come online" #3649

Checks

I've already read https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners-with-actions-runner-controller/troubleshooting-actions-runner-controller-errors and I'm sure my issue is not covered in the troubleshooting guide.
I am using charts that are officially provided

Controller Version

0.9.3

Deployment Method

Helm

Checks

This isn't a question or user support case (For Q&A and community support, go to Discussions).
I've read the Changelog before submitting this issue and I'm sure it's not due to any recently-introduced backward-incompatible changes

To Reproduce

No clear reproduction steps for the bug, as it is occasional. 
Team have noticed it occurs most often in the morning.

Describe the bug

In the example, on the CI piepline:

At 06:49 A job was suppose to be schedule on gm2.dind.large-b4j7w runner after the job "get-ecr-login-password"
During 40 minutes the job "unit-tests" is stuck in waiting for runner
At 07:40:43 in the controller we get the log "Created new ephemeral runner", which is named gm2.dind.large-b4j7w-runner-bsk5p. The runner will be use to run the job "unit-tests"

We have multiple cases of jobs waiting a long time for a runner, without any clear explanation.

Describe the expected behavior

Jobs is trigger
ARC controler create the runner
Runner is taking the job and start running it

Additional Context

There has been attempt to play around the 'minWorkers' configuration. of the runner-set to prevent the waiting issue.

Runner-set are deployed with helm using the values.yaml file:

githubConfigUrl: ${github_config_url}

Controller Logs

Logs would be best read when filtered on "gm2.dind.large-b4j7w"

"https://gist.github.com/victor-smg/1c7ed78e9702dd2389e98725c9ac37f5.js"

Runner Pod Logs

No relevant logs for the runner, as it is the lack of runner that is the issue

We are now facing this issue also, same version.

Bit more info, maybe will help.
So far we thought it is mostly problem in the morning, but we are impacted by it right now as well. In theory there was just GH Copilot outage in last hour, nothing about Actions or API, but still one of our runners is NOT fetching jobs. Seems like autoscalingrunnersets is not doing it's job correctly.

You can clearly see that there are 23 runners, failed are 22, but even if I try to restart job and get a hold of pod, don't see any.
What more surprising, other runners, using exactly same config (except mem/cpu limits) are working fine - even if they're bigger. So don't think there is no node capacity.

On top of that in logs, I see (read from bottom to top):

It's super strange, that pod was running just few seconds and than is deleted.

mohsen0 · 2024-07-12T08:26:10Z

is there a workaround for this? the issue effectively causes a very poor experience

keisari-ch · 2024-07-22T09:56:07Z

experiencing this issue aswell with a new deployment on AKS.
the runner job is never deployed. the only custom thing is the fact that there is a nodeSelector

We've seen the same issue. We noticed that there are other issues where this issue was discovered in older versions of actions runner controller, and one of them has a comment saying that the issue is fixed by restarting the listener.

This doesn't fix the issue for anyone, but as triage you can deploy a cron job with something like this:

apiVersion: batch/v1
kind: CronJob
metadata:
  name: actions-listener-restart-cron
  namespace: actions
spec:
  schedule: "*/5 * * * *"
  jobTemplate:
    spec:
      template:
        spec:
         serviceAccountName: your-service-account
         containers:
         - name: actions-listener-restart-pod
           image: bitnami/kubectl:v1.26.14
           imagePullPolicy: Always
           securityContext:
             allowPrivilegeEscalation: false
             capabilities:
               drop: ["ALL"]
             runAsUser: 999
           command:
           - /bin/sh
           - -c
           - kubectl delete pod -n actions -l app.kubernetes.io/component=runner-scale-set-listener
         restartPolicy: Never

You'll also need to define the ServiceAcccount and its role/rolebinding, but the above should get you started.

On our side, it somehow magically stopped to be an issue over 2 weeks ago. Since that time, no single job was not picked up (except around an hour, when we messed up our networking in AWS and you couldn't reach the Kubernetes cluster - but it was purely problem on network, which we caused).
So for now I can't really debug it more or add recommended restart, as it simply works.

ricardojdsilva87 · 2024-09-11T16:06:14Z

Hello, we have a similar situation on our runners.
We have basically the same template applied to all the different labels, the difference between them is basically the resources set.
We noticed that even deleting all the resources and reinstalling everything causes the same behaviour. Here are the logs for a working listener triggering new pods:

As you can see there are 3 entries of Created merge patch json for EphemeralRunnerSet update the first with replicas:null and the other 2 starting to patch the number of replicas into the ephemeralrunnerset.

The only difference to a non working job is that it does not have the second scale. After the first one with replicas:null it keeps listening for new events but does not scale any pods.

We are using the runnerscaleset: v0.8.3 with the ghcr.io/actions/actions-runner:2.316.1 image.

I even tried to patch manually the ephemeralrunnerset with no success or even increasing the minimum or runners from 0 to 2 on the autoscalingrunnerset the pods appear but are not assigned any jobs.

Any idea where should we look into? As it seems there is an issue between the listener pod and the ephemeralrunnerset but like mentioned even after deleting everything and recreating the same behaviour happens.

Thanks

ricardojdsilva87 · 2024-09-13T09:53:11Z

Hello everyone,
In our case the issue we create a separate Runners Group on GHE to register the listeners. For some reason even after deleting the entire deployment the listeners could not fetch any pending jobs until we deleted this Runner Group and Recreate it.
After that all the existing labels registered successfully and the jobs started right away.
Thanks

ricardojdsilva87 · 2024-10-24T11:21:25Z

Just an update, we kept seeing the listeners being offline on our github instance with no apparent reason. Deleting the autoscalingrunnerset made the listener to be recreated and be able to register again.
As soon as we do this, the jobs are picked up and new runners are created.
We are checking also on our github instance side what might be wrong, since we do not see no errors on the listeners/controller side and for the moment we've implemented a cronjob that deletes the autoscalingrunnerset every hour, checking first if there are any active runners for that label. If so the autoscalingrunnerset is not deleted, if no runners are present we delete the autoscalingrunnerset so it can register again.

Y0RI0 · 2024-11-18T08:30:52Z

I have the same issue and @ricardojdsilva87 comment will solve it. Listener does not report any error logs. Last thing it says (repeatedly) before dying suddenly is:

Preparing EphemeralRunnerSet update

I'm wondering if this has something to do with it, but it shouldn't matter if no jobs are running. Controller should be able to "see" that the listener is missing, kill the set, and recreate. So perhaps if a job is not reporting as exited, it will hang out waiting to delete ephemeral set (which also controls whether the listener exists or not)

actions-runner-controller/charts/gha-runner-scale-set-controller/values.yaml

Line 123 in 8b36ea9

updateStrategy: "immediate"

Referencing related issue: #3704

Additional details if it helps:

running with argocd
controller and runners are in separate NS
have set minimum runners to 2, so two seem to exist, but listener pod has died

ganchesp · 2025-01-07T14:09:25Z

we have experienced the same issue here:
we have 2 runner-scale-set for redundancy, both have same name as runner-scale-set, each has different runner group.
It used to work, but now workflow hanging with "waiting for runner come online". however, both runner-scale-set are online with green light.
We could not see any errors in the arc-system namespace, and it seems like there is no way to check out the cause.
For torubleshooting, we have uninstall both helm release of arc and runner-scale-set, and reinstall via helm both of them, but problem persists.

Any tips will be much appreciated!

nikola-jokic · 2025-05-07T13:02:10Z

Hey everyone, this should b resolved now. Can you please confirm you are not getting this error anymore?

nikola-jokic · 2025-05-07T13:06:22Z

I'll close this issue here since we are tracking it on the new issue #3953
Thank you for reporting it and please let us know if you are still experiencing the issue.
