Description

We are seeing that the reason a jenkins agent takes too long to start is that it cannot download and it is killed before doing it.

Research direction

Start by reviewing master-log.txt and launch-jenkins-agent-pod-log.txt to identify why the agent cannot download remoting.jar before it is killed. Then trace the agent startup and download configuration referenced by those logs and reproduce the failure if possible. Done means the agent reliably downloads remoting.jar and starts without timing out.
