通知孩子pid XXXX退出信号分段错误11，可能在/ etc / apache2中的coredump

我不断收到我的Apache日志中的跟随错误：

我试图通过执行以下操作来回溯：

我无法解决这个问题。

我也在apache上运行gdb，如下所示：

我不知道是否与这个问题有关，但只要我安装gdb，login时显示以下消息：

=> There were exceptions while processing one or more plugins. See /var/log/landscape/sysinfo.log for more @R_101_4045@ion.

sysinfo.log包含以下内容：

一些背景。

我正在运行一个WordPress网站closures我的VPS。 VPS是一个基于Ubuntu的LAMP服务器，安装了PERL和CURL。 我使用APC进行caching，但在安装APC之前出现了分段错误。 最后，我通过Google PageSpeed Service运行我的服务器，所以我已经安装了Apache 2.2的mod_remoteip mod，并有一个X-Forwarded-For头文件。

ulimit核心是无限的。 我的PHPinfo（）文件可以在这里find： http : //tecne.ws/11v

请协助。 这将不胜感激！

variables将被多次实例化

使用mod_rewrite隐藏在Web浏览器上访问的Python脚本的.py扩展名

.htaccess不加载CSS和JS

configurationshiro.ini进行JDBC连接

我怎样才能使用mod_rewrite删除后的一切？ （问号）在一个URL？

我有这个问题，并改变LogLevel warn在Apache配置LogLevel debug 。 在重启时，它似乎是在mod_deflate之后进行的。

在debian / ubuntu中关闭mod_deflate应该是sudo a2dismod deflate

我间接解决了这个问题 我把Nginx放在Apache的前面，我不再有分割错误。 在我看来，让Nginx在Apache面前更好。 清漆缓存也可能解决了这个问题。

经过整整一天的追查，没有解决方案的工作。 我最终把Apache变成了调试级别的日志记录，并立即注意到Google的mod_pagespeed有数百个通知/警告，用于尝试从Jetpack的Photon图像重写图像。

我做了一个简单的a2dismod pagespeed ，没有更多的分割错误。

也注意到我的网站实际上运行速度更快，关闭了mod pagespeed。

似乎有很多关于pagespeed的错误报告导致了分段错误。

不知道它只是mod_pagespeed或mod_pagespeed，wordpress和PHP的组合….但现在关闭问题没有了。

现在我已经完成了这个工作，现在也正在把所有的东西都移到Nginx上。 在Apache上跟踪错误总是变成一场噩梦，Nginx可以在几秒到几分钟内找到错误。

尝试设置

max_input_time = -1

在你的PHP.ini文件中。

从PHP.ini …

; Maximum amount of time each script may spend parsing request data.

我在Centos 6上遇到与Varnish> Apache> PHP-FPM相同的问题。

我通过在Apache中禁用KeepAlive来解决这个问题。
