PHP内存不足 - 崩溃的Apache？ [英] PHP Out of Memory - Crashes Apache?

问题描述

我运行PHP版本5.3.0和Apache：2.2.11

I am running PHP version 5.3.0 and Apache: 2.2.11

当我运行消耗大量内存（我认为）的PHP脚本 - 大循环等。我的Apache Web服务器报告崩溃

When I run PHP scripts that consume a lot of memory (I think) - large loops etc. My Apache web server reports a crash?!

[Sat Jan 02 00:51:30 2010] [notice] Parent: child process exited with status 255 -- Restarting.

我需要的地方增加内存？目前，我有内存设置为

Do I need to increase memory somewhere? I currently have memory set to

memory_limit = 512M 

PHP并没有抱怨这让我想到了别的东西吗？

PHP hasn't complained about this so I am thinking its something else?

感谢所有

这个错误在事件查看器中被记录在我的Windows机器：

脚本问题。我已经删除的URL。

Update 2

Script in question. I've removed the URL.

<?php error_reporting(E_ALL);

set_time_limit(300000);

echo 'start<br>';

include_once('simple_html_dom.php');

$FileHandle = fopen('tech-statistics3.csv', 'a+') or die("can't open file");

for($i =1; $i < 101; $i ++){
 // Create DOM from URL
 $html = file_get_html("http://www.x.com/$i");

 foreach($html->find('div[class=excerpt]') as $article) {

  $item0 = $article->children(1)->children(1)->children[0]->plaintext;

  $item1 = $article->children(1)->children(1)->children[0]->plaintext;

  $item2 = $article->children(1)->children(0)->children(0)->children(0)->plaintext;

  //$item3 = $article->children(1)->children(0)->children(0)->children[1]->children(0)->next_sibling();

  $stringa = trim($item0).",".trim($item1).",".trim($item2)."\r\n";

  fwrite($FileHandle, $stringa);

  echo $stringa.'<br>';
  echo '------------>'.$i;
 }
}

fclose($FileHandle);

echo '<b>End<br>';

?>

更新3

我使用PHP简单的HTML DOM解析器，我刚刚发现这一点：

Update 3

I am using the PHP Simple HTML DOM Parser and I have just found this:

<一个href=\"http://simplehtmldom.sourceforge.net/manual_faq.htm#memory_leak\">http://simplehtmldom.sourceforge.net/manual_faq.htm#memory_leak

我想我应该清除内存，否则会崩溃。现在测试。

I think I should be clearing memory otherwise it will crash. Testing now.

是的，这是一个内存泄漏！ ：）

Yep, it was a memory leak! :)

推荐答案

阿帕奇崩溃，由于这是由不打烊正在被反复使用的循环资源，以及脚本导致内存泄漏利用递归的。

Apache was crashing due to a memory leak which was caused by not closing a resource that was being used again and again in a for loop, as well as the script making use of recursion.
