Sometimes you get the message ERRNO-13 (permission denied) if JobScheduler run under Windows:ERRNO-13.jpg
To run a shell job, JobScheduler creates temporary files including the script to execute, the stderr and the stdout of a job etc. At the end of the job (no matter if the job was killed or ended normal) these temporary files will be deleted. Sometimes on windows machines it is not possible to delete this files, because another process (such a virus scanner or windows itself) locks them. In this case JobScheduler can't delete these files and logs ERRNO-13.
