I keep running into issues where DS does not finish closing a flat file and then the next step goes to use the file, and there is a contention issue causing jobs to fail.
I have been putting a pause in the jobs as I come across this, but it can happen anywhere and the pause doesnt always take care of it. Also if I am looping through and creating a series of 50 output files, adding small delays increases the completion time by quite a lot.
