      How to Reproduce

      • Create a simple job that does nothing
      • Create a simple MultiJob project with one phase, which contains the reference to the job, see multijob-config.png
      • Build the MultiJob

      You will see the stacktrace appearing several times (3 times), see logs-after-build.log

      Impact

      This is critical as when many jobs run at the same time, it is polluting at such extent that it slow down the Jenkins server and make it unresponsive.

            I am able to reproduce the JENKINS-45892 warning, though not the loading deadlock noted in JENKINS-48685, which I presume is random.

            I think this might be related to what we see in JENKINS-48685
