apache服务器不断重启

Question

我的 Apache 服务器每隔几秒/分钟就会死掉。这会杀死我的网站，并且不允许它们运行。我在 CentOS 上运行 VPS 服务。

有部分 error_log（更改 IP 和 DNS 名称）：

WARNING: MaxClients of 150 would require 6 servers,
 and would exceed the ServerLimit value of 2.
 Automatically lowering MaxClients to 50.  To increase,
 please see the ServerLimit directive.

有人能告诉我这个问题是什么吗？

Answer 1

Apache 告诉您问题是什么。你只需要倾听。

[Fri May 31 12:51:11 2013] [alert] (11)资源暂时不可用：apr_thread_create：无法创建工作线程

由于这是一个 VPS，我怀疑您达到了提供商强加的限制（可能是 RAM，可能是进程/线程数）。
联系您的提供商寻求帮助，以确定您遇到的限制和可能的解决方案。
