Apache假死，Apache维护，高手请进，谢谢
前几天，Apache还是每隔1天死一次，我一直在尝试解决，可这两天，每隔一个小时就死一次，如果在他死后，我不在进程中手动结束掉httpd.exe，便会出现下面的log：

如果在他死后，我立马手动结束掉httpd.exe进程，就会出现下面类似的log：

HTML code

......[Sun Aug 16 12:53:51 2009] [notice] Parent: child process exited with status 3221225477 -- Restarting.[Sun Aug 16 12:53:51 2009] [notice] Apache/2.2.4 (Win32) configured -- resuming normal operations[Sun Aug 16 12:53:51 2009] [notice] Server built: Jan  9 2007 23:17:20[Sun Aug 16 12:53:51 2009] [notice] Parent: Created child process 3300[Sun Aug 16 12:53:52 2009] [notice] Child 3300: Child process is running[Sun Aug 16 12:53:52 2009] [notice] Child 3300: Acquired the start mutex.[Sun Aug 16 12:53:52 2009] [notice] Child 3300: Starting 64 worker threads.[h:1

我知道是Apache优化的问题，但我一直在改那些参数，一直却没用，就像没改一样，

前段时间，我把后面注释掉的全都打开的，后来才给注释掉的。
服务器每日流量3000左右吧，最多不超过5000
求大侠救小第一命，不然要被老板宰啰
网上的资料我都看得差不多了，试过了都没用...
另外，服务器是windows2003的，2个G的内存，我看了下，cpu使用率最多不会超过50%，就算我手动结束掉进程，但那数字又立马窜得老高，

[解决办法]
深奥，！检查是不是程序问题，从错误报告来看，是由于进程发生冲突，造成服务器不断的重启，。仔细检查程序是不是有的地方没有做好。

此外，检查服务器是不是受到攻击。

从你每隔2天或者1天就出现这个问题来看，应该可以排除配置的原因，如果配置错误，要么就运行出错，要么就正常，一般不可能出现间隔性的错误，。

[解决办法]
关于apache的优化，推荐一篇：http://www.bsdlover.cn/html/36/n-336.html
------解决方案--------------------

PHP code

<IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 10</IfModule>
[解决办法]
看一下系统的其他记录，比如登录和访问记录，看是不是有人攻击。
[解决办法]
你去/php5/ext目录下看一看有没有这些dll.
如果你不需要这些dll，就去php.ini中去掉这些dll的加载，如果需要就去找dll，不一定默认在/php5/ext目录下的。
官网下载，不代表不需要自己去配置。

MaxRequestsPerChild 50表示当超过50个线程时，Apache会kill掉最旧的来回收资源。这个不算Apache重启。

[解决办法]
还有，既然你发现有人试图攻击就要防范，不一定别人取到你的用户密码才叫攻击，如果他不停访问你的服务器，会增加服务器的负荷，引起服务器宕机的。
[解决办法]
不有个apache专区么，这边解决不了就转到那边看看。
[解决办法]
是不是httpd.exe 100%cpu？
我的有时候也有这毛病据说apache 本身有这个问题
关注。。。。
[解决办法]
windows下apache是一直有这个问题的，建议楼主换成IIS或签到Linux服务器下。
[解决办法]
楼主都真么说了~ ~
排查问题不是ME强项YE~
我这电脑有时候apache就是启不来~老觉得是领导在监控我工作。
