      Description

      Hello,

      If the following pipeline script is run as a pipeline job in Jenkins, The instantiated class is not collected by the garbage collector:

      class asdf {
        void run () {}
      }
      
      new asdf().run()
      

      Even after a garbage collection is run using jcmd, the instantiated class is still there:

      $ jcmd <PID> GC.run
      
      # wait for garbage collection to complete
      
      $ jcmd <PID> GC.class_stats | grep asdf
      11804    13         0        640          48     3344          13       470      2472     1904      5008      6912 asdf
      

      With one class or a few classes, this issue might not lead to any problems. But our pipelines have a lot of classes and we're encountering a steady increase in the MetaSpace and OutOfMemoryExceptions (CompressedClassSpace) after every 2 to 3 weeks. Additionally the Metaspace increases by several GBs per week to about 10 GB in 2 to 3 weeks.

          Description Hello,

          If the following pipeline script is run as a pipeline job in Jenkins, The instantiated class is not collected by the garbage collector:
          {code:java}
          class asdf {
            void run () {}
          }

          new asdf().run()
          {code}
          Even after a garbage collection is run using jcmd, the instantiated class is still there:
          {noformat}
          $ jcmd <PID> GC.run

          # # wait for several minutes or even hours, since a GC.run only schedules a GC run, as far as I understand it.

          $ jcmd <PID> GC.class_stats | grep asdf
          11804 13 0 640 48 3344 13 470 2472 1904 5008 6912 asdf
          {noformat}
          With one class or a few classes, this issue might not lead to any problems. But our pipelines have a lot of classes and we're encountering a steady increase in the MetaSpace and OutOfMemoryExceptions (CompressedClassSpace) after every 2 to 3 weeks.

          Hello,

          If the following pipeline script is run as a pipeline job in Jenkins, The instantiated class is not collected by the garbage collector:
          {code:java}
          class asdf {
            void run () {}
          }

          new asdf().run()
          {code}
          Even after a garbage collection is run using jcmd, the instantiated class is still there:
          {noformat}
          $ jcmd <PID> GC.run

          # wait for garbage collection to complete

          $ jcmd <PID> GC.class_stats | grep asdf
          11804 13 0 640 48 3344 13 470 2472 1904 5008 6912 asdf
          {noformat}
          With one class or a few classes, this issue might not lead to any problems. But our pipelines have a lot of classes and we're encountering a steady increase in the MetaSpace and OutOfMemoryExceptions (CompressedClassSpace) after every 2 to 3 weeks.

          Hello,

          If the following pipeline script is run as a pipeline job in Jenkins, The instantiated class is not collected by the garbage collector:
          {code:java}
          class asdf {
            void run () {}
          }

          new asdf().run()
          {code}
          Even after a garbage collection is run using jcmd, the instantiated class is still there:
          {noformat}
          $ jcmd <PID> GC.run

          # wait for garbage collection to complete

          $ jcmd <PID> GC.class_stats | grep asdf
          11804 13 0 640 48 3344 13 470 2472 1904 5008 6912 asdf
          {noformat}
          With one class or a few classes, this issue might not lead to any problems. But our pipelines have a lot of classes and we're encountering a steady increase in the MetaSpace and OutOfMemoryExceptions (CompressedClassSpace) after every 2 to 3 weeks.

          {noformat}
          Hello,

          If the following pipeline script is run as a pipeline job in Jenkins, The instantiated class is not collected by the garbage collector:
          {code:java}
          class asdf {
            void run () {}
          }

          new asdf().run()
          {code}
          Even after a garbage collection is run using jcmd, the instantiated class is still there:
          {noformat}
          $ jcmd <PID> GC.run

          # wait for garbage collection to complete

          $ jcmd <PID> GC.class_stats | grep asdf
          11804 13 0 640 48 3344 13 470 2472 1904 5008 6912 asdf
          {noformat}
          With one class or a few classes, this issue might not lead to any problems. But our pipelines have a lot of classes and we're encountering a steady increase in the MetaSpace and OutOfMemoryExceptions (CompressedClassSpace) after every 2 to 3 weeks. Additionally the Metaspace increases by several GBs per week to about 10 GB in 2 to 3 weeks.

           

          Some more information about the environment:
           * *Operating System:* Jenkins-Master runs in a debian-slim docker container
           * *JRE/JDK vendors and versions:* OpenJDK 11.0.6
           * *Jenkins and plugin versions*
           ** Jenkins 2.235.3

          I tested this with both official docker images: jenkins/jenkins:jdk11 and jenkins/jenkins:2.259-slim (jdk 8).

          While the problem of Stefan Hölzle also occures on jenkins:jdk11 (with nothing else installed than workflow-job and workflow-cps), it does not occure on the jdk 8 image (jenkins:2.259-slim).

          jochenafuerbacher Jochen A. Fürbacher added a comment - I tested this with both official docker images: jenkins/jenkins:jdk11 and jenkins/jenkins:2.259-slim (jdk 8). While the problem of Stefan Hölzle also occures on jenkins:jdk11 (with nothing else installed than workflow-job and workflow-cps ), it does not occure on the jdk 8 image ( jenkins:2.259-slim ).

          Same behavior with AdoptOpenJDK13 and Oracle JDK 11. Also changing the GC via -XX:+UseG1GC or -XX:+UseParallelGC didn't solve the problem.

          Can some take care of this issue? Seems to be a serious bug when not using java 8.

          Due to this issue we need to restart our jenksin master instance every couple of days.

          Just quick update. The root cause of memory leak was :

          • Usage of prometheus plugin (Metrics Processes)
          • Autoreload of configuration-as-code thru the sidecar container within the same pod .. which results a DDoS "Handling POST /..."
          • jobs which call organizationFolder in a loop for huge number of  projects.

          The issue was fixed by

          • removing prometheus plugin. (prometheus operator is enough for us)
          • disabling auto-reload of config-as-code
          • BUT keeping jobs as it's it

          Hallo Abdennour Toumi,
          I don't see how one of your root causes might fit to the example given in the description.
          Could you try the example from the description in order to verify that your fixes apply to this issue.
