IceStorm problem

[freshman]

when I used IceStorm,there is such a exception:

Ice.ConnectionRefusedException

what's the matter? does it because the message stream is too large?
if I use the thread's sleep function,the speed of transmit message is too slow,what can I do?
can IceStorm use more than one socket at one time?thank you very much!!

Connection refused simply means that the server or service is not running, or it is not running on the host/port specified by the client's proxy.

Try to run with network tracing (Ice.Trace.Network=2) to find out where the server or service listens, and where the client tries to connect to.
