I've encountered this issue as well when using the API. Some scripts were using a 5 second sleep default to allow for copying the file to the output directory, but I found that I needed up to 15 seconds (occasionally that's not even enough).

Hi all,

So I have a tool that I am writing a wrapper script for that produces a directory of images as one of its outputs. This directory gets created just fine in the job_working_directory, but then when the job finishes and the contents of the job_working_directory are copied, the copy of the images directory is a zero-length *file*. I seem to recall having this problem before and finding a solution to it, but now I can't seem to find it. Any ideas?

- Nik.
