Description

When retrieving files from FTP server, the client will open a data connection with an in-use port and failed in server, but the client hung in this function(no error, no exception, even the connection is closed due to timeout by server). This will occur after successfully getting hundreds of files (I have more than 4000 small files to be transferred, it will fail after 100+ or 300+ or 400+ files. It always fail to FTP 4000 small files.)
