信号11退出PHP-FPM和连续“

我有一个至强E5504 2ghz和8GB内存的Hpnetworking服务器，使用freebsd 8.2-p9 amd64， nginx 1.2.1 ， PHP 5.3.14 ，mysql 5.5.25，apc，memcached和其他软件包安装使用freebsd端口。 （在该消息结束时的conf文件）

我的麻烦很简单，我在/ var / log / messages中有很多“退出信号11”，当php-fpm子女死亡时，我的网站上有“502网关错误”，这真的很无聊，因为我已经在一天的很多错误，在这个php-fpm conf我已经强制它在一个沉重的configuration与150的PHP-FPM的孩子在静态模式下，pm.max_requests = 10000000，但在我的PHP-FPM日志我发现每个孩子：

[19-Jul-2012 18:58:14.666913] NOTICE: pid 84563, fpm_children_make(), line 421: [pool www] child 84717 started [19-Jul-2012 18:58:14.666984] DEBUG: pid 84563, fpm_event_loop(), line 409: event module triggered 1 events [19-Jul-2012 18:58:17.403217] DEBUG: pid 84563, fpm_event_loop(), line 409: event module triggered 2 events [19-Jul-2012 18:58:17.407442] DEBUG: pid 84563, fpm_got_signal(), line 72: received SIGCHLD [19-Jul-2012 18:58:17.407552] WARNING: pid 84563, fpm_children_bury(), line 252: [pool www] child 84563 exited on signal 11 (SIGSEGV) after 39.849444 seconds from start 

并在同一个pid的/ var / log / message中：

 Jul 19 18:58:14 web1 kernel: pid 84563 (php-fpm), uid 1001: exited on signal 11 

可以肯定的是，这不是一个configuration文件（php.ini和php-fpm.conf）的麻烦，我恢复了它与我在档案中find的原始的一个，但没有，我试图使用spawn-fcgi，但同样的麻烦！

• Ubuntu上的init.d启动时没有启动守护进程的内核
• 如何可靠地采取Java堆转储？
• 获取/debugging由oom-killer杀死的进程的核心转储
• 如何在断开连接时从apache获得核心转储
• Linux上的非阻塞核心转储？

当我尝试生成一个运行“ gdb / usr / local / sbin / php-fpm ”的php-fpm.core时，当退出信号11时， php-fpm主进程退出，同时退出信号5核心转储） “（只有当我运行它扔GDB！），在这里日志和gdb回溯结果：

• / var / log / messages（见上）
• PHP-fpm.log
• GDB

正如你在上一个链接中看到的，那是最后一行：

 #659 0x0000000801534de0 in ?? () from /lib/libc.so.7 #660 0x0000000000000001 in ?? () #661 0x00007fffffffec08 in ?? () #662 0x000000000000000f in ?? () Cannot access memory at address 0x800000000000 

有任何想法吗？

谢谢！
