Hi, it could be a RuntimeException that the application is throwing. I would suggest putting a try/catch block in setup, bsp/compute and cleanup and log it as error log. You would then find the exception stacktrace in the tasklogs/JobID/*.log. I am looking into scenarios why the exception won't be logged.
