> Add 1 + 2 = 3
> Ping 
> Sum 1 + 2 + 1 = 4
> Run on multicast 3 : multicast://239.255.3.2:6142?group=cluster1
> Add 1 + 2 = 3
> Ping 
> Sum 1 + 2 + 1 = 4

> "Run on single point server 1 : ejbd://9.123.237.141:4201
> Add 1 + 2 = 3
> Ping 
> Sum 1 + 2 + 1 = 4" this line still exist, seems no break, but in theory, if 9.123.237.141
shutdown, apps cann't acess loadbean via ejbd://9.123.237.141
