Since you did not show the actual sniffer trace, I can only guess that
you are probably using Active mode transfers, the server is not able
to connect to the FTP client's listening socket, and the operation is
timing out before the server's error message can be received.  Is
there a router/firewall involved?  FTP is very unfriendly to those
because of its use of multiple socket connections.  Try using Passive
mode transfers, if you are not already, as they are a little more
friendly since the connections are all outbound instead of inbound.
If that still does not help, then you need to provide more detailed
information.  There is not enough to diagnose your problem adequately
enough yet.
