Apache服务器总是崩溃，“抓SIGTERM，关停”(Apache server keeps cr

这只是开始发生三周多前。 我的网站的内容并没有改变，这是使用MySQL作为后端只是一个phpBB论坛。

在一切都没有改变一年多，但最近，每两天左右的时间，服务器只是关闭并不能在所有的访问，我不得不通知我的服务提供商物理重新启动机器。

这似乎是依赖于这些SIGTERM错误，我在日志中找到。 问题是我不知道如何解决这些事情或找到问题的根源是我在这方面的技能缺乏。

任何人有任何想法可能是怎么回事？

阿帕奇/ 2.2.3（CentOS的）

20051115

Linux的2.6.18-028stab057.4＃1 SMP周五8月1日10时47分59秒2008 MSD x86_64的

从错误日志：【孙年11月1 15点18分53秒2009] [声明]抓住SIGTERM，关停

不能完全肯定这是什么导致了我，我的问题，但它听起来并不像一件好事。

如果需要，我可以发布更多的日志信息

Answer 1:

SIGTERM是用来重新启动Apache（前提是它在init进程自动重新启动安装程序）： http://httpd.apache.org/docs/2.2/stopping.html

您在日志中看到的条目几乎肯定是因为有您的供应商使用SIGTERM用于这一目的。 如果是真正的崩溃，甚至不提供静态内容，那么这听起来像是某种线程/连接耗尽问题的。 也许一个拒绝服务保持连接打开？

绝对应该是你的供应商进行调查。

Answer 2:

我有神秘SIGTERM停产在我们的LAMP服务器，它原来是一个自定义的PHP模块，这是由版本不匹配造成的错误。 它是由在发生故障的时间寻找在Apache访问/错误日志中发现的。 不要忘了打开错误日志记录。

Answer 3:

你有没有问过你的供应商进行调查？ 我认为这不是一个专用的服务器，

在它面前，这似乎是一个安全异常，并有人为正试图利用它/或有一个过程，在这是造成这个设定的时间运行，你能想到的任何服务器上运行，每2天？ 日志记录工具？

SIGTERM是发送到进程，以请求其终止的信号。 为SIGTERM符号常数在头文件signal.h中定义。 符号信号名字，因为信号数字可以跨平台有所不同，但在绝大多数的系统，SIGTERM是信号＃15。

Answer 4:

从这个页面 ：

我发现这个信息：

该过程的mod_fastcgi经理是不是特别耐心，但（这里有改进的余地），并且由于它具有关闭操作，发送SIGTERM到所有的FastCGI应用它负责的。 Apache将重新启动进程管理器，它会重新启动其管理的应用程序（如如果服务器刚启动）。 SIGTERM是，好了，SIGTERM - 你的应用程序应该很快退出。

什么这意味着对我来说，如果数据库I / O，或CGI脚本的其他部分，未能及时做出反应（即获得与数据量的增长要慢），这是的mod_fastcgi杀死脚本.... ..是其他人如何解释这些文档还是我缺少什么..
