Thanks you both... after correcting my BIO_do_connect (and all
read/write following it) -> adding retries (as Girish pointed), it
works just fine.
Now I'll check the errors, mentioned by Darryl, to make it more clear,
not just to retry until some counter runs out.
Thanks.

And if you do this:
while(1) {
int rv = BIO_do_connect(m_pBio);
if(rv < 0) {
// Fix this line below with correct detection for a fatal or
non-fatal error, if BIO_do_connect() returns a fatal error we want to
abort, if BIO_do_connect() returns an expected non-fatal error we need
to delay and try again.
if(errno != EINPROGRESS)
break; // fatal error
// wait a bit and try again
sleep(1);
}
}
I am not familiar with BIO and nonbocking connects but the the connect()
system call will return -1/EINPROGRESS when the connect is not yet
connected but still working on establishing a connection.
Just a thought for you.
