Runner Registration Being Deleted In the Middle of Running Jobs

[wagenet]

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

This happens consistently on our setup but I have no idea how to reproduce elsewhere.

Describe the bug

In the middle of jobs running they often are unexpectedly canceled. The job logs will show a line like Error: Process completed with exit code 1. which is often preceded by context canceled. The Workflow Summary Annotations will also contain:

The runner has received a shutdown signal. This can happen when the runner service is stopped, or a manually started runner is canceled.

In the runner logs we see:

Failed to create a session. The runner registration has been deleted from the server, please re-configure. Runner registrations are automatically deleted for runners that have not connected to the service recently.

It is very surprising that this happens while jobs are actively running.

Describe the expected behavior

I would expect that runners not lose their registration while actively running jobs.

@wagenet I was also experiencing this problem and the solution I found was to go to version 0.9.0 and it solved my problem.

[wagenet]

@aiell0 are you suggesting downgrading?

[aiell0]

@aiell0 are you suggesting downgrading?

Yes, that's what I had to do unfortunately.

[Karandash8]

I have the same problem running in kubernetes mode. Happens on both 0.9.3 and 0.9.0 versions. Container jobs randomly terminate without any obvious reason.

[thomaschaplin]

Any update on this? I'm seeing the same issue but cannot replicate on demand.
Running v0.9.3

[ali-kafel]

Running into this issue as well on v0.9.3

[epwilkins]

I was running into this as well and it ended up being a node pressure issue. We were consuming all of the available node disk space and so k8s was evicting the runner.

[abhilashsupare]

I also observed the same issue on v0.9.3. In my case, I checked all Node instance parameters under the threshold.
Still, it's failing with same issue

[abhilashsupare]

any update on this issue

following up

[jonathan-fileread]

@Link- we're forced to consistently re-queue jobs till completion, any assistance would be really helpful!
