Apache子进程退出，状态为255 [英] Apache child process exited with status 255

问题描述

经过大量的搜索，尝试，修复，等待和哭泣，在我放弃之前，我想在这里抓住这个错误的最后机会...

After lot of searching, trying, fixing, waiting and crying and before I give up, I want to take the last chance here for this bug...

我们正在 Microsoft Windows Server 2012，Apache/2.4.6(Win64)OpenSSL/1.0.1e PHP/5.5.1 上运行.

在24小时内，至少会定期发生5至10次Apache崩溃并重新启动.通常两次.因为PHP崩溃了.

Periodically, at least 5-10 times within 24 hours, Apache crashing and restarting. Mostly twice. Because PHP crashed.

整个应用程序都是PHP，因此将php配置为 FastCGI 并不能解决问题:Apache不会崩溃，但是PHP会崩溃.

The whole application is PHP, so configuring php as FastCGI won't solve the problem: Apache will not crash but PHP will.

这里有更多信息:

• 在PHP中，没有什么特别的日志，并且崩溃前没有任何模式.
• 并发连接也不会影响该问题-即使我们的用户很少，也会发生这种情况.
• MySQL?但是没有错误指出这一点还是我在错误的地方看?
• Windows?如何弄清楚?
• PHP/Apache配置?好吧，还有什么..为什么?
• 外星人...
• In PHP log nothing special and no pattern before crash.
• Also concurrent connections not affecting the problem - it's happens even when we have very few users.
• MySQL? But no errors pointing to this or I looking in wrong place?
• Windows? How to figure out?
• PHP/Apache configuration? Well, what else.. and why?
• Aliens...

主要问题是为什么PHP崩溃?..

The main question is why PHP is crashing?..

提前谢谢！

推荐答案

就我而言，日志中仅此而已. 仅限:

In my case, nothing more in logs. Only:

 Parent: child process XXXX exited with status 255 -- Restarting

问题出在重定向代码中:

Problem was in redirect code:

<?php
    header('HTTP/1.1 304 Not Modified');
    exit();
?>

此代码停止apache服务并启动新进程. 但是并不是所有的时间...有时工作得很好...有时会崩溃:(

This code stops apache service and start new processes. But not all time... sometimes worked fine... sometimes crashes :(

正确的代码是:

<?php
    header('HTTP/1.1 304 Not Modified');
    die();
?>

有关以下内容的更多信息: PHP:利用exit();或者死();标头("Location:");

More informations about: PHP: Utilizing exit(); or die(); after header("Location: ");
