FTP server weird behavior

[sebas]

Creating a directory work fine. But when uploading files using FTP the problem is that it cycles from the client perspective.

Once a file has been uploaded the client starts to upload it again and then ask if it should be overwritten and again and again.

It happens with the server not just one domain.

Here is a log of a session.
