it is explained in the FAQ about getting "Need more sources" that
"if the person who has the file you’re trying to download has too many people requesting files, he won’t be able to serve any more file requests, and your connection will be refused."

when "your connection [is] refused" does it mean that you will be put on hold and your computer will keep trying until the person is able to serve you or
does it mean that once you are refused your computer stops trying and you will have to try later on your own?

thanks so much
