Hi, I'm running a CI on a k8s cluster using Jenkins to schedule jobs.

It works pretty fine for a year whereas it totally broke down these weeks.

Currently, we found the jenkins pipeline always stuck at the last step and could wait for years. After gstack the threads, lots threads busy in futex_wait_queue_me:

what is jenkins doing right here? which lock is jenkins waiting for?

We guess it might be something wrong with our Jenkins Settings but couldnt find any clue.... Anyone please help this out!!
