Multiple self hosted runners working with same label but only one of then picks jobs from queue

[Ozan Kizildogan]

Hello,

We are using bitbucket pipelines with self hosted runner to build docker images which is done with a docker in docker image and it works fine.

However when we test the distribution of same pipeline jobs amongst 3 runners which have the same labels only 1 of them picks up the job from queue the others remain in "PENDING" state. ( manual triggered pipeline)

Is this a known issue?

In relation to the problem, I followed the instructions and installed bitbucket Kubernetes auto scaler, but even though it authenticates and deployments run, the self hosted runner does not get scaled.

Could you please help on both topics?

Thanks
