Cancelled by driver indicates that the Job Driver process failed, probably
because of a problem in the application CR.

No output is not right if some was expected.

Are there any custom environmental parameters required for the application
code? DUCC does *not* pass on the environment active when submitting work.
Any parameters must be explicitly specified.

Is DUCC running as user=ducc? If so, is ducc_ling properly configured to
spawn application processes as the submitting user?

This error is because the Job Driver process terminated.
