Hello I am getting the following error in job runs that take place in kubernetes. I guess that the error happens when the job fails to get the status of a task. After that error in the job, the task is being killed even though it was running without problems. I think that this error occurs when I run 3 or more jobs concurrently but this should not be a load to my nodes. Does anybody know what could be its cause and how could it be fixed?
Task 'TaskPreprocessing': Exception encountered during task execution!
