open failed: EBUSY (Device or resource busy)

Question

I have a strange error in my App.

In my app it is possible to download a zipFile, read the content as what it is and also delete it. Its doesn\'t matter what exactly

Answer 1

It seems to be a lingering filesystem lock. I fixed it without touching my code, I think it was by unplugging my USB cable and re-plugging it in.
