      Description

      We are seeing the bug originally described in JENKINS-62181. Remote agents hang on launch. This is using a supposedly patched release.

      In our experience, we are seeing a correct launch of this agent the first time after Jenkins is rebooted. Then, after the agent times out (in-demand delay 1, idle delay 5) and goes down, it cannot be restarting, it deadlocks on launch.

      It hangs here:

      <===[JENKINS REMOTING CAPACITY]===>channel started
      Remoting version: 4.3
      This is a Unix agent

      I don't know how to put in a test for Java deadlocks. Please advise. This is blocking usage.

            Yes, it seems to work now. At first, I still had some hiccups (on far fewer slaves) since there were still some (hung up) java processes running on the slaves but after a restart of those, all of them are up again.

            I have upgraded to version 2.253 and we are still experiencing problems with this exact issue. After upgrading and restarting more than half of our nodes deadlock in the manner described above. I have not been able to identify a procedure that will bring them up again dependably. Is anyone else having better luck at this?

            Jesse Glick I just attached one, it's from the same Jenkins instance that Vegar Andersen refers to.
