I am trying to do parallel active mode FTP uploads with the multi
interface and detected a strange behaviour.
The first upload of each connection timeout's waiting for the server to
connect. Retrying with
the same easy handle then starts the upload immediately.

Am I missing something?

thanks
Patrick

<code>
        curl_easy_setopt(item_handles[i], CURLOPT_UPLOAD, 1);
        curl_easy_setopt(item_handles[i], CURLOPT_USERPWD,
loginInfo.c_str());
        curl_easy_setopt(item_handles[i],
CURLOPT_FTP_CREATE_MISSING_DIRS, 1);
        curl_easy_setopt(item_handles[i], CURLOPT_FTPPORT, "192.168.2.224");
        curl_easy_setopt(item_handles[i], CURLOPT_FTP_USE_EPRT, 0);
        curl_easy_setopt(item_handles[i], CURLOPT_TIMEOUT, 30);
        curl_easy_setopt(item_handles[i], CURLOPT_FTP_RESPONSE_TIMEOUT, 30);
        curl_easy_setopt(item_handles[i], CURLOPT_VERBOSE, 1);
        curl_easy_setopt(item_handles[i], CURLOPT_URL,
itemDestinationPath.c_str());
        curl_easy_setopt(item_handles[i], CURLOPT_READDATA, file);
