SMSC HTTP issue on many smsc

Hi,

I'm currently benchmarking kannel/cvs-20090615 with 40 http smsc type generic
with a host 127.0.0.1 and 40 differents ports.

The thing is that the 30 firsts smsc are working and responding normaly
like this exemple:
#) telnet 127.0.0.1 7188
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

HTTP/1.1 400 Bad Request
Server: Kannel/cvs-20090615
Date: Mon, 15 Jun 2009 13:55:22 GMT
Content-Length: 0
Connection: close

Connection closed by foreign host.


- The 10 nexts have the port open but never responds.
#) telnet 127.0.0.1 7817
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.



^C^C^C^C^C^C



Did someone have noticed this before ?

regards

Vincent.
