To Reproduce

this error happens randomly

Describe the bug

Job randomly gets stuck with the msg "Job is waiting for a runner from XXX to come online" cancel the job and rerun will fix it.

Observations: 1: Compared with jobs without issue, for this job gets stuck, there is no job started msgs get received on the listener pod (i.e. it only gets job available, job assigned, and then stuck util cancelled manually..) 2. for the job gets stuck, the EphemeralRunnerSet gets patched to 1 replica and then immediately gets patched to null, see logs below

2024-05-06T13:44:52Z INFO listener-app.worker.kubernetesworker Created merge patch json for EphemeralRunnerSet update {"json": "{\"spec\":{\"patchID\":1,\"replicas\":1}}"}
2024-05-06T13:44:52Z INFO listener-app.worker.kubernetesworker Scaling ephemeral runner set {"assigned job": 1, "decision": 1, "min": 0, "max": 20, "currentRunnerCount": 0, "jobsCompleted": 0}
2024-05-06T13:44:52Z INFO listener-app.worker.kubernetesworker Ephemeral runner set scaled. {"namespace": "arc-runners", "name": "basic-runner-622tx", "replicas": 1}
