That is a good question! 🙂
I don't know the answer to this question but here is what i would do.
First try submitting a job that isn't that complicated to test and see if its the code that you are submitting that is causing the issue. Here is a simple program that will always work .
Proc print data=sashelp.cars;
run;
Put this code in a sas program and run it, then schedule it as a job and see if you are getting the same issue. If you are, then there is something wrong with the system(so maybe a bug). You will need to speak to your sas administrator to assist you.
If the code above works, then you know that the code you are executing is the issue and you need to figure out why but doing further testing.
Hope this helps.
