Hi,

In addition to my last mail in which I gave a piece of the code, which seems
problematic, here I am sending the corresponding logfile as Thomas
suggested.
Just as reminder, I will repeat the code:


----------------------------------------------------------------------------
----

1. First I start with:

beginLogging();
initAll();
connectToPoolElement();
//as a result, a global DataSocket is created which is nonzero. This is
the same as in examplepu.

2. I send some data 'buffer'.

sendToPoolElement(buffer);
//this is successfully transmitted as I can see with Ethereal. Also, the
SCTP receiver responds back with SACK + echoed 'buffer'.

3. I start listening to incoming messages:

FD_ZERO(&readfdset);
FD_SET(DataSocket, &readfdset);

timeout.tv_sec = 2;
timeout.tv_usec = 0;

result = rspSelect(DataSocket + 1, &readfdset, NULL, NULL, &timeout);
//exactly as in the examplepu;

After this I always get result=0, there are no incoming messages at
DataSocket and the program exits.

----------------------------------------------------------------------------
----


Hope this helps.
