cron info sent a weird email

Question

Hi

I got this email from cron info of my server.

"`client_errors' has different size in shared object, consider re-linking"

what is this ?

this cron job is just a simple email script

this is the script

include("../admin/connect.php"); 
require("../class.phpmailer.php");

$from = "[email protected]";
$fromname = "Me";

    $mail = new PHPMailer(true); //New instance, with exceptions enabled
$mail->IsSMTP();                           // tell the class to use SMTP
    $mail->SMTPAuth   = true;                  // enable SMTP authentication
    $mail->Port       = 587;                    // set the SMTP server port
    $mail->Host       = "smtp.gmail.com"; // SMTP server
    $mail->Username   = "********";     // SMTP server username
    $mail->Password   = "********";            // SMTP server password
    $mail->SMTPSecure = "tls"; // sets the prefix to the server
    $mail->IsSendmail();  // tell the class to use Sendmail


    $mail->From       = $from;
    $mail->FromName   = $fromname;

    $mail->Subject  = "Hi";

$edate = date("Y-m-d");
$query  = "SELECT * FROM `set` WHERE expire = '$edate'";
$result = MYSQL_QUERY($query);

while ($row = mysql_fetch_array ($result))
{

    $body .= "<pr>Hello<br /><br />";
$body .= "Hope everything is ok,<br />";

    $text_body  = "To view the message, please use an HTML compatible email viewer!";

    $mail->Body    = $body;
    $mail->AltBody = $text_body;
    $mail->AddAddress($row['email']);


    $mail->Send();
    $mail->ClearAddresses();

}

thanks

Answer 1

Something you are running expects a variable (structure or array, probably) to have a particular size N. Unfortunately, the shared library providing the value of that variable has a different size M. The request to 're-link' is perhaps a little naïve; it probably means recompile and relink using the new headers, etc.

So, some program used in your script needs to be rebuilt.

In light of the amended question:

I think it could be a problem. One thing to worry about is whether the PHP that is run by cron has the correct environment - cron does not set very much environment. It could be executing one PHP but trying to load a library from another, or something weird like that.

My standard advice for running cron jobs is always to run a shell script, which sets the environment if necessary before running the 'real' task. This also makes it easier to debug.

{
...environment setting...
env   # debug only
pwd   # debug only
date  # debug only
...exec the real program...
} >/tmp/log.$$ 2>&1
