When starting a background job an unproblematic error message like this could occur in the output of the background job log:

sys.stdin.close() IOError: [Errno 9] Bad file descriptor

This was caused by an unclean stdin/stdout/stderr handling during job startup since commit b15dfeb619c14c925b66f2a3437d213852204975.
