simple socket server example on cyclone II dev kit

Hi, I am trying to use simple socket server example on cyclone II dev kit.

It seems to work BUT :

when i send over 41 characters through ethernet (crossed câble) , dev kit goes to malfunction.

I receive random characters and communication hangs.

It is like there is too many characters. Too much work to do for Nios II + IP stack + microC/OS II.

Have you faced to this problem ?

Is there an example of Simple Socket server PLus (that enables FTP, TFTP, ...) for Cyclone II dev kit ?
