다중 CURL 요청에서 랜덤 500 오류

Question

curl_multi를 통해 웹 서비스에서 hal + json 데이터를 가져 와서 Bootstrap Typeahead를 채우려합니다. 이 코드를 실행할 때마다 curl_multi에서 내 요청 중 일부는 500이 될 것이고, 일부는 필요한 데이터를 반환 할 것입니다. 500 개는 완전히 무작위입니다. 다음 번에 페이지를로드 할 때 다른 쿼리가 500이됩니다 (그리고 오류가 발생하지 않습니다). 왜 그런 일이 계속 발생합니까?

// array of curl handles

왜이 일이 계속 않습니다

<?php 
$curlurl = 'https://service.domain.com/'.$_POST['customer-name'].'/contact?callback=?'; 
$cuurl = singleRequest($curlurl); 
global $contacts_typeahead_data; 
$contacts_typeahead_data = array(); 
$clinks = $cuurl['_links']['https://service.domain.com/rel/contacts']; 
for ($i=0; $i < count($clinks); $i++) { 
     $data[] = 'https://service.domain.com'.$clinks[$i]['href'].'?callback=?'; 
}; 
print_r($data); 
$datar = multiRequest($data); 
print_r($datar);  
foreach($datar as $c){ 
     $cs = json_decode($c, true);?> 

     <option value="<?php echo $cs['id']; ?>"><?php echo $cs['id'].' ('.$cs['info'][0]['name'].')'; ?></option> 
     <?php $contacts_typeahead_data[] = $cs['id'].' ('.$cs['info'][0]['name'].')'; 
}?> 

그리고 여기가 http://www.phpied.com/simultaneuos-http-requests-in-php-with-curl/ 기반으로 singleRequest 및 multiRequest에 코드입니다?

요청을 보내는 서버에서 이러한 일이 발생합니다. 은 일 수 있습니다.
