Rick Liu created an issue   Jenkins / JENKINS-53880 Build step trigger pipeline job hangs when master node set to zero executors Issue Type: Bug Assignee: Unassigned Components: core Created: 2018-10-02 20:57 Environment: Ubuntu 16.04 Jenkins Core v2.121.3 Priority: Minor Reporter: Rick Liu When master node is set to zero exectuors, a matrix job triggers a pipeline job (with blocking) doesn't work. From Matrix job console, it would show: Waiting for the completion of "<PIPELINE_JOB_NAME>". But the pipeline job doesn't start and it doesn't have queue jobs either. It's just like the trigger was not sent, but the matrix job is waiting for return indefinitely. Only from Jenkins master jenkins.log, you can see: Oct 02, 2018 1:27:29 PM hudson.model.Executor resetWorkUnit WARNING: Executor #-1 for master grabbed hudson.model.queue.WorkUnit@2cbaff74[work=PIPELINE_JOB] from queue but master went off-line before the task's worker thread started. No termination trace available.
