This is probably related to "Build queue hangs after timer task error". It seems he started a new thread now that he knows the reason of the jenkins build hanging out.
But I might be wrong and may be something completely different. Never used the Jenkins plugin, but I thought it created slaves on demand. Probably it can be limited to some max amount. And I don't know how it bodes with cluster-autoscaler, but depending your use case that can help too. On Fri, Aug 10, 2018 at 09:35:34PM +0000, Agrawal, Punit wrote: > +1 to Tims answer.
