O.K. I wiil try to test other ftp client and server.

Please see the output of "netstat -na" when stuck. (below)

CONFIG_NETFILER is diabled in my test configuration
,conntrack modules is not loaded.
(CONFIG_IP_DCCP, CONFIG_IP_SCTP, CONFIG_TIPC, CONFIG_IPV6 is
also disabled) 

 
> What kind of mode do you use? e.g. PORT/EPRT/LPRT/PASV/EPSV/LPSV

PASV mode.

Other communication works properly.
Actually, I can start other ftp session on other console of the same PC.

I only need to do the killall command.
