simple_socket_server fail on ep2c35

The simple_socket_server hangs on our ep2c35 develop board with lan9111, as in the attachments. The application program includes ucosii RTOS and lwip, uneable DHCP, using 192.168.1.128 as its static ip . 

I have get success on quartusii 5.0/niosii 5.0, but when I update to quartusii 6.0/niosii 6.0, it hangs . I don't there needs some change on simple_socket_server_syslib setting.
