Thank you for trying to resolve the issue. However, I have just tried to up-load again and I have the same problem. This seems to be an issue that happens every now and then. Let me know if you find the bug.
Best regards Andrei
I am actually using FTP client called SyberDuck, which simillarly as FreeZilla logs on Galaxy. So the issue is somewhere between this FTP client and the interface on Galaxy ...at some point the client stops uploading and there is no chance to restart.
