Unfortunately it is not shaped and consistently fluctuates in speeds. This sometimes causes problems when I am uploading large files in size i.e. The client will try to upload a file from my computer to the server. Because of the file size, the upload attempt will fail. After a few tries the file will become dead locked, which in my opinion is the clients doing as it does not seem to release the file physically after an attempt has failed. It then displays a ""critical error: file is in use"" and it cannot upload the file after that. This actually happens quite often to me. To fix this I have to close the client and service in task manager. Please can you have a look into it." Bug report closed normal FileZilla Client outdated critical error Windows Vista 64bit
