jenkins 2.19.4
durable-task 1.12
Linux server
Windows slave
java 1.8.0_51
Pipeline jobs occasionally hang on bat steps. This seems similar to JENKINS-34150 but we are using durable-task 1.12 which has the fix for that.
Thread dump from the job (after 18 hours):
Thread #26
at DSL.bat(awaiting process completion in C:\j\w\<folder>\<job>@tmp\durable-56b1eae1 on <slave>)
at WorkflowScript.run(WorkflowScript:349)
at DSL.withEnv(Native Method)
at WorkflowScript.run(WorkflowScript:242)
at DSL.stage(Native Method)
at WorkflowScript.run(WorkflowScript:156)
at DSL.node(running on <slave>)
at WorkflowScript.run(WorkflowScript:34)
The bat step is running a batch file:
cmd /c call test.bat ....
which in turn is running a python script which (in this case) is throwing an exception (I can see from inspecting log files on the slave). Looking on the slave the "durable-56b1eae1" folder is present with jenkins-log.txt, jenkins-main.bat and jenkins-wrap.bat inside of it. There is no sign of the batch process on the slave so I presume that it has completed. The build continues to occupy a slot on the executor. There are also several flyweight tasks from the matrix plugin on the same slave.
Please let me know if there is anything else I can do to help diagnose this.
