Re: framing layer error

The problem seems to be intermittent, so I don't know what is going on.


what I do is this;  I post a bunch of data URI encoded and send it with 
curl. On the server side there's a php script that reads that data and 
sticks it in a MySQL data base.

(I am looking for something to point out to the webservice,  to have 
them fix).


This is what I do client-side:

    //curl_easy_setopt(curl, CURLOPT_URL, 
"http://seismicvibe.org/upload/PSNA-V56-post.php");
    curl_easy_setopt(curl, CURLOPT_URL, CURL_URL);

    // Now specify the POST data
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, chnnlURI);

    // hush hush
    //curl_easy_setopt(curl, CURLOPT_NOBODY, 1);
    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, connectCheck);
    // we pass our 'chunk' struct to the callback function
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, (void *)curlRespBuff);

    // Perform the request, res will get the return code
    res = curl_easy_perform(curl);

    // Check for errors
    if (res != CURLE_OK) {
       sprintf(logMsg, "curl_easy_perform() failed: %s", 
curl_easy_strerror(res));
       log_message(LOG_FILE, logMsg);
       }
//   else
//      printf("response: %s\n", curlRespBuff);

    // always cleanup
//   curl_easy_cleanup(curl);
    }
//curl_global_cleanup();
return 0;


The curl object gets created outside this function, gets re-used, so I 
do the cleanup outside too.


the url in the curl command connects to a php script,  that reads the 
url encoded data and sticks it in a data base.


Since it seemed to work agin yesterday, I think, like you suggested,  it 
is a server side issue.
