All FD's write to the same spool. When the schedule runs the job, it is not on its own, however, when I have been running it by hand, then it is the only job running. > >>> It's a little bit surprising to see an error text of Success here...

This is the only one with a script. Surely if it has started to transfer data, the RST will not take place as it it no longer idle (just a thought).
