libwww problem with connect()

Hello,
 
I have a problem with an internal bank API that in turn uses libwww for its connection between the client and the server.
 
My setup is as follows:
    SunOS szur0039dap 5.8 Generic_117000-05 sun4us sparc FJSV,GPUSC-M
    CC from SUNWspro v8
    libwww 5.4.0
    Compiled as 32 bit
    Also using ACE/TAO for communications with otehr systems in the same process:
 
The client uses the link "  <http://fusiongateway.swissbank.com/dqeservlet/dqegateway> http://fusiongateway.swissbank.com/dqeservlet/dqegateway" to connect.
 
My big program, in which I'm trying to upgrade the internal bank API doesn't work; the "connect()" call in HTTCP.c fails. I the wrote a small test program (that also uses CORBA) to see if it works there (and it does).
 
I have truss-ed the 2 process. As you can see from the output included below, one doesn work and results in a close plus my log of "Caught unknown exception" while the one that works goes on to POST the HTTP reques.
 
As far as I can tell both sockets get created OK and in the same way. The only obvious difference is that the one that doesn't work is always above 20 (22 or 26) and the one that does work is below 15 (12 or 14).
 
ANY HELP WOULD BE GREATLY APPRECIATED.
 
Many thanks in advance,
Andrei Lenkei
