We have test jobs hanging on ec2 slaves indefinitely when the jobs are trying to clone ws from master using clone-workspace-scm plugin or publish html reports to master using htmlpublisher plugin. I don't think the issue is related to these two plugins though.

       

      We also notice that this issue mostly happens after the ec2 slave is up for a few days, i.e. if we take down the current slave and create a new instance, the jobs will run successfully at the begining, but start hanging after a few days. So I suspect that something is clogged over time.

       

      Our test jobs have the same pipeline: clone workspace -> run maven surefire for testing -> publish test results using html publisher

       

      Some issues that may be relative: 

      https://issues.jenkins-ci.org/browse/JENKINS-5977

      https://issues.jenkins-ci.org/browse/JENKINS-57119

       

      Any help would be much appreciated

       

      Update:

      We now shorten the Idle termination time so that we have new instances more often and find some pattern in this hanging behaviour.

      It appears to happen everyday around 11:00-11:30 AM UTC. We originally have two test jobs scheduled around 11:00 AM UTC. But for testing purpose, we changed the schedule for some other test jobs to 11:00 AM as well. The conclusion we get is that ANY job runs at that time in ec2 cloud will time out (job timeout set to 2 hours) after maven surefire tests and hang on html publish. Once the jobs time out, any new test jobs scheduled after that will hang on cloning workspace. If we move the jobs scheduled around 11:00 AM UTC to master (also in AWS), none of the jobs will hang. Also, if we run these test jobs at a different time in ec2 cloud, they will finish successfully as well.

          Description Original: We have test jobs hanging on ec2 slaves indefinitely when the jobs are trying to clone ws from master using clone-workspace-scm plugin or publish html reports to master using htmlpublisher plugin. I don't think the issue is related to these two plugins though.

           

          We also notice that this issue mostly happens after the ec2 slave is up for a few days, i.e. if we take down the current slave and create a new instance, the jobs will run successfully at the begining, but start hanging after a few days. So I suspect that something is clogged over time.

           

          Our test jobs have the same pipeline: clone workspace -> run maven surefire for testing -> publish test results using html publisher

           

          Some issues that may be relative: 

          https://issues.jenkins-ci.org/browse/JENKINS-5977

          https://issues.jenkins-ci.org/browse/JENKINS-57119

           

          Any help would be much appreciated

           

          Update:

          We now shorten the Idle termination time so that we have new instances more often and find some pattern in this hanging behaviour.

          It appears to happen everyday around 11:00-11:30 AM UTC. We originally have two test jobs scheduled around 11:00 AM UTC. But for testing purpose, we changed the schedule for some other test jobs to 11:00 AM as well. The conclusion we get is that ANY job runs at that time in ec2 cloud will time out (job timeout set to 2 hours) after maven surefire tests and hang on html publish. Once the jobs time out, any new test jobs scheduled after that will hang on cloning workspace. If we move the jobs scheduled around 11:00 AM UTC to master (also in AWS), none of the jobs will hang. Also, if we run these test jobs at a different time in ec2 cloud, they will finish successfully as well.
