apache error.log中的“ [notice]子pid XXXX退出信号分段错误11”

如何解决apache error.log中的“ [notice]子pid XXXX退出信号分段错误11”

将gdb附加到httpd子进程之一，然后重新加载或继续工作并等待崩溃，然后查看回溯。做这样的事情：

$ ps -ef|grep httpd
0     681     1   0 10:38pm ??         0:00.45 /Applications/MAMP/Library/bin/httpd -k start
501   690   681   0 10:38pm ??         0:00.02 /Applications/MAMP/Library/bin/httpd -k start

…

现在将gdb附加到子进程之一，在本例中为PID 690（列为UID，PID，PPID等）

$ sudo gdb
(gdb) attach 690
Attaching to process 690.
Reading symbols for shared libraries . done
Reading symbols for shared libraries ....................... done
0x9568ce29 in accept$NOCANCEL$UNIX2003 ()
(gdb) c
Continuing.

等待崩溃…然后：

(gdb) backtrace

要么

(gdb) backtrace full

应该给你一些线索，这是怎么回事。如果提交错误报告，则应包括回溯。

如果崩溃难以重现，则最好将Apache配置为仅使用一个子进程来处理请求。配置是这样的：

StartServers 1
MinSpareServers 1
MaxSpareServers 1

解决方法

我正在使用Apache / PHP / MySQL堆栈。作为CakePHP框架使用。

我时不时地得到一个空白的白页。我无法通过Cake对其进行调试，因此我查看了apache error.log，这是我得到的：

这是什么细分错误，如何解决？

更新：

PHP Version 5.3.4,OSX local development
Server version: Apache/2.2.17 (Unix)
CakePhp: 1.3.10
