Message when I debug my app

When I debug My app I get a lot of messages like this:

05-10 11:35:18.911 11753 11958 W System.err: remove failed: ENOENT (No such file or directory) : /data/user/0/com.deem/cache/http/a557f0553fa74b2a8d6eb248f308da11.1

Here a screenshot from the terminal:

What does it means?

Do you have a small test case that produce this?
