XWin opens no connection (except for xdmcp). It's a server and will only 
react on incoming connections.

The error results from a program which tries to open many connections at 
a time (SYN request). these connections must be acknowledged by the 
receiving end (SYN,ACK reply). as long as this reply was not received, 
the connection is in a half-open state. Windows XP does only allow 10 of 
these half-open connections. File sharing programs or worms which try to 
send mass mail may cause this problem. I don't see any reason why XWin 
would cause this behaviour.
