Apache2重新加载和系统崩溃

重新加载Apache2导致Ubuntu 11.04挂起/崩溃。

Load average was 32 

CPU内核 ：8

型号 ：Intel Xeon E5620

内存 ：16 GB

• 更新内核后没有检测到Adaptec RAIDarrays？
• Slackware 10.1在内核3.x引导时挂起
• 没有在syslog中看到内核消息
• CentOS 6 – 内核3从CentOS 7回购？
• dspam崩溃与“一般保护”内核错误

内核 ：2.6.38-13-通用

我从上面的日志了解这些事情，可能不正确：

• 原因与Apache相关，因为它显示Apache进程ID。
• 发生在CPU 5上。
• 内核不受污染
• 由于一般保护错误，需要硬复位才能恢复。

任何人都可以帮助我进一步分析这个堆栈跟踪更多的原因。
