Jenkins normal behaviour? Hard drive running at 100% highest activity time?

      Description

      The Jenkins Master Java.exe process is constantly running and reading hundreds of different workflow.xml files, thus causing Windows to become less responsive.

      The hard drive active time is showing 100% and disk i/o running under 50% both the Windows Task Manager and Windows Resource monitor.

       

      The two main resources are

      Java.exe and system are running.

       

      An example of the files constantly being read/cycle through by the Jenkins Java.exe process (taken from the Windows Resource Monitor):

      Java.exe  PID:4332   C:\Program files(x86)\Jenkins\Jobs\Create-mac\builds\16\workflow\34.xml

       

      There are many XML files, that it is cycling through within all our build jobs/pipelines and it never ends - it has been running for about 4 days (that we have noticed).

      Has any one seen this with Jenkins via Windows Resource monitor before?

          It is definitely not a normal behavior. Please provide a Jenkins version (the one specified does not exist) and Pipeline plugin versions.

          Jenkins version 2.204.1 and Delivery Pipeline plugin 1.3.2, if that you asking for?  Thanks

          Jenkins heap space jvm  -Xmx 1024m, and using default 32bit java within Jenkins_home.

           

           Change version to 64bit Java and increase  heap memory  -Xmx 4g, would this help?

          Needs thread dumps to see what's happening: https://wiki.jenkins.io/display/JENKINS/Obtaining+a+thread+dump

          Xmx matters more than Xms IMO. Make sure it's large enough to keep build records in memory.
