Hi Daniel,
Unfortunately at this point I cannot share the source code with all.
But at a very high level it is like this:

curlOps()
{
    //init curl handle
    int sock;
    m_curlHandle = curl_easy_init();
    //set CONNECT_ONLY option on the curl Handle
    curl_easy_setopt(m_curlHandle, CURLOPT_CONNECT_ONLY, 1L);
    //connect to HTTPS server
    //set options for server
    curl_easy_perform(m_curlHandle);
    curl_easy_getinfo(m_curlHandle, CURLINFO_LASTSOCKET, &sock);
    //perform some operations
    //reads and writes basically using curl_easy_recv, curl_easy_send
    //disconnect
    curl_easy_cleanup(m_curlHandle);
}

performAction()
{
    curl_global_init(CURL_GLOBAL_ALL);
    while(some_condition)
    {
        curlOps();
    }
    curl_global_cleanup();
}

The connection establishment (curl_easy_perform) and retrieving raw socket
also work fine always. I have been going through the logs and some more info
I gathered was that:
Initially, after a successful connection, I do a write operation using
curl_easy_send() and then do a curl_easy_recv(). the send operation is also
going fine but I get this error in the receive operation.

Also, If there is a delay between the closing and opening a new connection,
things are working fine, but here in one scenario we issue a rapid restart
of the client. This is causing problems.

I googled for this and found some more info:
*easy_connection() *method in easy.c logs this error (*Failed to get recent
socket*) when the sockfd is -1 and the returned curl code is 1. But here my
connection is going through fine and the initial curl_easy_send() is also
being successful so I am baffled as to what could have gone wrong

Thanks
Karthik
