卷曲PHP - 奇怪的内部服务器错误

Question

I have 2 servers. Server 1 has the engine/api. Server 2 has apache2 and my website.

From the website I try do a simple curl to the engine. If the curl lasts more than ~15sec I get internal server error. If I run this script from bash (not using a browser) I get status 200 and an answer. When I run this script from localhost to the engine it runs ok. But, when I want connect from my server via browser to engine - I get the internal server error after 15s.

I don't have any information in apache2 error_log. In php.ini I have the execution time = 120 and in apache I have 300 timeout. Do you have any idea what is wrong? (My server runs under debian lenny.) Sorry for my bad English.

$data = "Test text";
$_data['post'] = 'source_text='.urlencode($data);
$_data['url'] = ENGINE_PATH;
$_data['access'] = HTACCESS_LOGIN.':'.HTACCESS_PASSWORD;
$_curl = curl_init();

if(!empty($_data['post'])){
    curl_setopt($_curl, CURLOPT_POST, 1);
    curl_setopt($_curl, CURLOPT_POSTFIELDS, $_data['post']);
}

if(substr($_data['url'],0,5) == 'https'){
    curl_setopt( $_curl, CURLOPT_SSL_VERIFYPEER, false );
}

curl_setopt($_curl, CURLOPT_URL, $_data['url']);
curl_setopt($_curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($_curl, CURLOPT_TIMEOUT, 60);
curl_setopt($_curl, CURLOPT_CONNECTTIMEOUT, 60);
curl_setopt($_curl, CURLOPT_HEADER, 0);
curl_setopt($_curl, CURLOPT_FOLLOWLOCATION, 1);

if(!empty($_data['access'])){
    curl_setopt( $_curl, CURLOPT_USERPWD, $_data['access']);
}

$agent = 'Mozilla/5.0 (X11; U; Linux x86_64; pl-PL; rv:1.9.2.22) Gecko/20110905 Ubuntu/10.04 (lucid) Firefox/3.6.22';

if(!empty($_SERVER['HTTP_USER_AGENT'])){
    $agent = $_SERVER['HTTP_USER_AGENT'];
}

curl_setopt($_curl, CURLOPT_USERAGENT, $agent);
curl_setopt($_curl, CURLOPT_FAILONERROR, 1);

$data = curl_exec($_curl);

EDIT

I do simple script php -

 echo '1';
 sleep(16);
 echo '2';

But I get 500 error too. I try this in apache2 and lighttpd. Than I pretty sure - this is error configuration on system...

EDIT Problem is solved. The problem was configuration of server pound. Thank you for help.

Carefully check the logs. To display the error, add the following code:

ini_set('error_reporting', E_ALL);
error_reporting(E_ALL);
ini_set('log_errors', true);
ini_set('html_errors', false);
ini_set('error_log', dirname(__FILE__).'script_error.log');
ini_set('display_errors', true);
