Does the job exit with an error or a warning?
If it's an error i'll agree with the other suggestions to fix the error by its source.
If it' a warning, and you want to allow your batch-flows to complete with a warning, then you can edit the sasbatch.bat file.
\SAS\Config\Lev1\SASApp\BatchServer\sasbatch.bat
Just remove the REM in the last four lines as stated in the comments in the file.
This is on a windows platform but I assume that you can do something similar if it's another platform.
