Perhaps a permanently hung connection because timeout is zero (=disabled?)?
Seems plausible since FIN only means “I’m done sending” also called a “half close”.
FTP has different data and command connections so the server may not have an outstanding read to detect the data connection break.
But.. it should still clean up both when the command connection dies
