我有一个休闲问题：Apache 每个孩子吃很多 ram。

我知道你会说没有什么可担心的，因为交换不使用，但我认为它现在不使用。

我想这就是帮助我解决这个问题所需的所有信息。我认为虚拟内存很大，同样的资源。ram的消费量一直在增加。也许是内存泄漏，因为我看到编译了很多静态模块。
有人可以帮我解决这个问题吗？先感谢您。

如您所见，内存使用量从 res( 135 到 145)m 增长，并且会一直增长到内存结束。你确定我设置了这个选项：
<IfModule prefork.c>
StartServers 8
MinSpareServers 5
MaxSpareServers 25
ServerLimit 80
MaxClients 80
MaxRequestsPerChild 4000
</IfModule>
KeepAliveTimeout 6
MaxKeepAliveRequests 100
KeepAlive On
是正确的？也许我应该减少其中一些？
另一个困扰我的问题：例如，我将静态模块mod_negotiation.c编译为 apache，并将相同的模块加载为动态模块。我加载了重复的模块是否正常。但是当我想从 httpd.conf 中删除动态模块（mod_negotiation.c）然后重新启动 apache 错误出现。现在我不能告诉这个错误信息，因为我不能重新启动 apache :(
你好：）这是重启apache后的内存使用情况：

我将尝试从源代码编译 apache 到最新版本。谢谢大家的帮助。
从 Apache 2.2.15 变更日志来看， 2.2.15 中修复了内存泄漏，但如果您的顶部输出是在 apache 启动之后，从我的角度来看，它确实很大。
您尝试过工人配置吗？
您可以在 httpd 二进制文件上添加 ldd 工具的输出吗？
