Title: Message Title

Pierre Beitz created an issue   Jenkins / JENKINS-53158 Pipelines leak OneOffExecutors when triggered on a temporary offline master Issue Type: Bug Assignee: Unassigned Components: core, pipeline Created: 2018-08-21 11:12 Environment: * Version: 2.121.3 * workflow-aggregator:2.5 * workflow-cps:2.54 'Pipeline: Groovy' Priority: Major Reporter: Pierre Beitz When a Pipeline is triggered while the master node has been put temporarily offline, a OneOff (flyweight) executor is leaked. As I'm unsure whether the issue lies in core or in the pipelines at put both components.   Environment Version: 2.121.3 workflow-aggregator:2.5 workflow-cps:2.54 'Pipeline: Groovy'   Steps to reproduce Create a simple Pipeline Job, eg: node('master') { sh 'echo hello' } Put the master node temporary offline Trigger the Pipeline build Put the master node back online Observe the leaked executor   Observations This executor has the following characteristics: Executor #-1(-1) Active? false Likely Stuck? false Interrupted? false Busy? false Owner? hudson.model.Hudson$MasterComputer@228777fd Current Work Unit? null Causes Of Interruption? [] Idle Start Milliseconds? 1534847122799 Progress: -1 Asynchronous Execution: null Executable: null executorOwner: hudson.model.Hudson$MasterComputer@228777fd tiedJobs: [] Jenkins logs show: Executor #-1 for master grabbed hudson.model.queue.WorkUnit@4891a81f[work=hello] from queue but master went off-line before the task's worker thread started. No termination trace available. Pipeline logs show nothing: Démarré par l'utilisateur admin Running in Durability level: MAX_SURVIVABILITY [Pipeline] node Running on Jenkins in /Users/pierrebeitz/cbsupporthome/jenkins-home/workspace/hello [Pipeline] { [Pipeline] sh [hello] Running shell script + echo hello hello [Pipeline] } [Pipeline] // node [Pipeline] End of Pipeline Finished: SUCCESS Workaround A restart of Jenkins will cleanup the executors.       Add Comment   This message was sent by Atlassian JIRA (v7.10.1#710002-sha1:6efc396) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
