mysqli_multi_query verliert connection

[Lynky]

Hallo zusammen,

ich verwende die mysqli_multi_query funktion um alte datensaetze aus einer tabelle zu loeschen und neue datensaetze einzufuegen. Mein Code:

  
...  
    $Query  = "DELETE FROM `resumes_education` WHERE resume_id = ".$this->POSTV['res_id'].";";  
    $Query .= "DELETE FROM `resumes_certifications` WHERE resume_id = ".$this->POSTV['res_id'].";";  
    $Query .= "DELETE FROM `resumes_skills` WHERE resume_id = ".$this->POSTV['res_id'];  
   $res1  = mysqli_multi_query($MYSQL_LINK, $Query);  
   $Query = '';  
   if (isset($this->POSTV['resume_edu_institution'])) {  
    foreach ($this->POSTV['resume_edu_institution'] as $idx => $instvals) {  
       $Query .= "INSERT INTO `resumes_education` (  
              `resume_id`,  
            `institution` ,  
            `location` ,  
            `certificate` ,  
            `year` ,  
            `qualifications`  
            )  
        VALUES (  
            ".myesc($this->POSTV['res_id']).",  
            ".myesc($this->POSTV['resume_edu_institution'][$idx]).",  
            ".myesc($this->POSTV['resume_edu_certificate'][$idx]).",  
            ".myesc($this->POSTV['resume_edu_location'][$idx]).",  
            ".myesc($this->POSTV['resume_edu_year'][$idx]).",  
            ".myesc($this->POSTV['resume_edu_qualifications'][$idx])."  
            );";  
       }  
     }  
  
   $res2 = true;  
   if ($Query != '') {  
    echo $Query;  
     $res2 = mysqli_multi_query($MYSQL_LINK, $Query);  
     }  
...  

Die DELETE statements in der ersten Query werden ausgefuehrt, nicht allerdings die INSERTS. Die geben mir folgende Fehlermeldung:

2013: Lost connection to MySQL server during query

Wenn ich nur _ein_ DELETE ausfuehre ("welches" spielt keine Rolle) und nur _ein_ INSERT dann funktioniert die Geschichte. Wuerde jedoch nur ungern auf meine foreach-schleife verzichten!

Weiss jemand Rat?

Gruesse,
