      Hello,

      I use Jenkins with parallel builds to checkout many packages.

      Example:

      parallel (
      build(build("CheckOut-Package", PACKAGE_NAME: "Package1");
      build(build("CheckOut-Package", PACKAGE_NAME: "Package2");
      ...
      build(build("CheckOut-Package", PACKAGE_NAME: "Package10");
      )
      

      Each of these jobs calls the log rotator when finished.
      Some time, next log appears:

      SEVERE: Executor threw an exception
      java.util.NoSuchElementException
              at jenkins.model.lazy.LazyLoadRunMapEntrySet$1.next(LazyLoadRunMapEntrySet.java:76)
              at jenkins.model.lazy.LazyLoadRunMapEntrySet$1.next(LazyLoadRunMapEntrySet.java:63)
              at java.util.AbstractMap$2$1.next(AbstractMap.java:385)
              at hudson.util.RunList.subList(RunList.java:139)
              at hudson.tasks.LogRotator.perform(LogRotator.java:125)
              at hudson.model.Job.logRotate(Job.java:467)
              at hudson.model.Run.execute(Run.java:1808)
              at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:43)
              at hudson.model.ResourceController.execute(ResourceController.java:98)
              at hudson.model.Executor.run(Executor.java:374)
      

      In this case, Jenkins does not detect that the job is finished even if it is indeed finished, and stay stucked.
      Since log Rotator should not be a blocking task, I added an exception catch in this PR:
      https://github.com/jenkinsci/jenkins/pull/1790

      That was enough on my side to handle this very recurrent problem.
