Well, I don know if it is actually a problem or not. Just to understand.
In the screenshot attached you can see that the file downloading has more than 430 sources, but only 39 are connected, actually all the not connected sources appear like you can see in the screenshot, "Unknown state".
For this file and for some others is always like that, but not all of them, other files download fine and quite fast. The screenshot has been taken after 14 hours of connection, but after two days is the same.
The Statistic window says that the maximum of allowed connections (750 in this case, just to try...) has never been reached.
Obviously the file is dowloading from some days but only 20 % has downloaded.
Is it normal? or there is something wrong?
