I am working on a code which requires data to be sent for each URL. I used
following code to send the data. But after 120-130 requests CURL is throwing
CURL_SOCKET_BAD in connect::singleipconnect(..). It is failing at
verifyconnect(). It starts working again after 140 if i add delay for CURL
errors.

Code
---------------------------------------------------------------
static const char *urls[] = {
"http://www.xyz1.com",
"http://www.xyz2.com",
"http://www.xyz3.com",
"http://www.xyz4.com",
"http://www.xyz5.com",
 };

 #define URLsCOUNT sizeof(urls)/sizeof(char*) /* total number of transfers
to do */

for(int i=0;i<30;i++)
{
    for(int j=0; j<URLsCOUNT ;j++)
    {
        sendData(urls[i],getData(i));
    }
}

void sendData(char* url, char* data)
{
    CURL* curl = curl_easy_init();
    curl_easy_setopt(curl, CURLOPT_URL, url);
    curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, true);
    curl_easy_setopt(curl, CURLOPT_AUTOREFERER, true);
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);
    curl_easy_setopt(curl, CURLOPT_LOCALPORTFUNCTION, getRandomPort);
    curl_easy_setopt(curl, CURLOPT_LOCALPORTDATA, this);
    curl_easy_setopt(curl, CURLOPT_LOCALPORTRANGE, (long) 511);

    //cleanup
    CURLcode curlRes=curl_easy_perform(curl);
    curl_easy_cleanup(curl);

    if (curlRes == CURLE_COULDNT_CONNECT){
        //Got error and delay & retry
    }
}
