      In changelog we found that with Jenkins version 2.47 Groovy was updated to 2.4.8 "to address memory leak issue".

      Possibly this issue is related to

      https://issues.apache.org/jira/browse/GROOVY-8067: Possible deadlock when creating new ClassInfo entries in the cache

      which is in Groovy 2.4.8 and solved in 2.4.9

       

       

          [JENKINS-43197] Deadlock when many jobs running

          Dane Kantner added a comment - - edited

          I think I'm having the same issue after upgrading past 2.47.  I'm having constant deadlocks on monitoring jobs to the point I'm about to do a restore from backup or rebuild of the full system if not resolved shortly. The jobs themselves use Groovy to read a file that is used in GroovyAxis, just a small list of branch names.  Additionally I use the Extensible choice plug-in to read almost the same list from a txt file via groovy.  These text files are dynamically updated every few minutes but I have turned the updating off to rule out that file being locked at the time/etc. This has worked well for at least a year. After the updates, it seems to be all plug-ins that use Groovy that are of issue, though. When this happens I cannot load any jobs that use the extensible choice groovy plug-in either. The only real resolution seems to be a service restart. I've tried re-configuring threads to only 1/slave, and the opposite as well, adding slaves, etc. and it doesn't seem to be an issue of shortage of resources.

          The deadlocks seem to be a combination of jobs that are getting stuck in waiting on org.codehaus.groovy.reflection.GroovyClassValuePreJava7$GroovyClassValuePreJava7Segment@XYZ and then in turn that is causing other jobs to be stuck waiting on a list that job seems to hold hostage.  waiting on org.codehaus.groovy.reflection.GroovyClassValuePreJava7$GroovyClassValuePreJava7Segment@f3b6160   – that part is a big unexplainable as there's no real need it needs to be any sort of shared object. They are groovy scripts loading a groovyaxis of 3-5 branch names to that is then ran on an axis.

          The workaround to start Jenkins with -Dgroovy.use.classvalue=true proposed at  GROOVY-8067 improved situation a lot for us.

          We experiencing the same issue. Today 2 Jobs stuck, after some time Jenkins was unresponsive.

          Threaddump -> https://pastebin.com/WTF9QUPu (JIRA upload failed)

          Jenkins 2.57
          OpenJDK 1.8.0_121
          Debian Jessie

          Trying the workaround, let's see if it occurs again

          Thanks Hans, I've added -Dgroovy.use.classvalue=true to jenkins.xml config for startup w/ that flag and it seems to have resolved the Groovy issues...

           

          Is there a process used to update to the latest groovy library to the newer version where they've fixed this to actually resolve the underlying issue? I'm assuming it's not just upgraded because of regression resources?

          Jenkins 2.61 upgraded to Groovy 2.4.11. This change was considered too risky for LTS inclusion, so we decided on 2.60 as the LTS baseline after 2.46.x.

          I doubt a Groovy backport qualifies for LTS. Still, summoning olivergondza.

          In terms of this issue, if the Groovy upgrade fixes it, it should be gone in 2.61 and newer. Please report your results on these versions of Jenkins.

          The next LTS baseline will be Jenkins 2.73, so if the change in 2.61 resolved this issue, it will be obsolete then.

          Responses to JENKINS-33358 indicate this has been fixed. After months without further responses I'll assume that is the case here as well.
