Upload holding at complete size

In my Uploads, one user has a file that has uploaded, is showing the size of the uploaded files is the same as the file size, that there are 0s remaining, but it is not showing complete. I have tried to remove the upload, but to no avail. Any suggestions or ideas as to what the issue may be, I am at a loss.

The client actually waits for the downloader to close the connection when the download is complete (up to 30 seconds.) to ensure that all the file transfer data has been received on their end. Some older versions of the client have a bug that relates to recognizing when a download actually finishes and so fail to close the connection. This could account for what you're seeing.
