blocks|key|3102798|text|但这种情况很少发生，但有时应用程序使用的第三方接口限制了连接的数量。我们无法找出原因，除非有更多的细节，如您的应用程序的内容，错误代码apache或HTTP返回。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3102799|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

But it rarely happens but sometimes the amount of connection is restricted by the third-party interface being used by the application. We are unable to figure out the reason unless having more details like what content of your app, and the error code apache or HTTP returning.

blocks|key|765511|text|这种情况很难跟踪，特别是在Windows上，在Windows上，诊断工具并不像在其他平台上那么容易使用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|765512|我认为您可以尝试通过运行服务器和客户端来检查防病毒，在几个小时内根本没有防病毒，或者在挂起时禁用和重新启用防病毒。|765513|除此之外，您还需要确定错误发生的位置：|765514|在连接阶段(Windows是问题所在)|unordered-list-item|765515|在响应阶段(Apache是问题所在--试着摆弄孩子的产卵参数)|765516|在管理阶段(PHP是问题所在--您可能可以通过更改PHP作为模块和PHP+CGI应用程序的设置来检查这一点)。|765517|在响应阶段(即连接到SQL服务器)。您可以通过设置一些使用会话、数据库和输出缓冲的不同组合的页面来检查这一点，并查看即使在挂起应用程序时，这些页面是否仍然可访问。|765518|的最后一个例子，如果有一个页面，如|765519|<?php+print+date("H:i:s");+phpinfo();+?>|code-block|syntax|javascript|765520|即使应用程序没有响应，仍然可以访问并正确刷新(这就是date()命令的原因)，这表明Windows、Apache和PHP是“无辜的”，或者SQL服务器有问题，或者您没有正确地与它进行接口。例如，驻留PHP模块正在积累到SQL服务器的连接，而不是释放它们，因此在一段时间后您需要停止Apache+(从而释放模块)并重新启动。|765521|如果是这样的话，即使它不是一个“真正的”修复，您也可以设置Apache，这样所有的孩子都会死，并且在少量的请求之后被替换(一旦它是150次，但是当泄漏几乎全部消失时，我相信默认的是0-+Apache的孩子不再死了。你看，我可能记错了)。|765522|entityMap^0|0|0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|11|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|12|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|13|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|14|8|@]|9|@]|A|$]]|$1|I|3|J|5|H|7|15|8|@]|9|@]|A|$]]|$1|K|3|L|5|H|7|16|8|@]|9|@]|A|$]]|$1|M|3|N|5|H|7|17|8|@]|9|@]|A|$]]|$1|O|3|P|5|6|7|18|8|@]|9|@]|A|$]]|$1|Q|3|R|5|S|7|19|8|@]|9|@]|A|$T|U]]|$1|V|3|W|5|6|7|1A|8|@]|9|@]|A|$]]|$1|X|3|Y|5|6|7|1B|8|@]|9|@]|A|$]]|$1|Z|3|-4|5|6|7|1C|8|@]|9|@]|A|$]]]|10|$]]

This kind of situations is difficult to track, especially on Windows where diagnostic tools aren't as readily available as on other platforms.

I suppose you can try and check the antivirus by either running server and clients with no antivirus at all for some hours, or disabling and re-enabling the antivirus when the hangup occurs.

Apart from that, you would need to pinpoint where the error occurs:

<ul>
<li>in the connection stage (Windows OS is the problem)</li>
<li>in the response stage (Apache is the problem - try fiddling with the child spawning parameters)</li>
<li>in the management stage (PHP is the problem - you can probably check this by changing the setup from PHP-as-a-module, and PHP-as-CGI-application)</li>
<li>in the response stage (that is, connection to the SQL server). You can check this by setting up some pages that use different combinations of session, database, and output buffering and see whether those pages remain reachable even when the application is hung up.</li>
</ul>

For an example of the last, if a page such as

<pre><code>&lt;?php print date("H:i:s"); phpinfo(); ?&gt;
</code></pre>

remains reachable and correctly refreshes (that's why the date() command) even when the app does not respond, this demonstrates that Windows, Apache and PHP are "innocent", and either the SQL server has issues, or you do not interface with it correctly. It might be for example be the case (though unlikely in this instance) that the resident PHP module is accumulating connections to the SQL server and not releasing them, so that after a while you need to stop Apache (thereby freeing the module) and restart.

If this were the case, even if it's not a "real" fix, you can set up Apache so that all children die and are replaced after a small number of requests (once it was 150, but when leaks all but disappeared, I believe that the default became 0 -- Apache children no longer die. Check it out, I might well misremember).

I have setup a local server on a regular desktop (not a server desktop) and have 3-4 client machines accessing the local web application I developed from the server via a WIFI router (server is connected to router via cable. All clients via WIFI).

When two of the clients are connected to the application all is well, but when a third (or more) machine joins in there are periods where each machine does not get any service from the server (the application webpage remains loading until I manually reset Apache on the server via services). At times the server responds when one of the clients refresh their page but most of the time I have to perform a reset of the Apache server.

This occurs roughly once an hour on average (6 hours of continuous usage) as the clients are using the application.

Server is running Windows 7 and Apache v2.4 with PHP v5.4

Server and all client machines are running AVG internet security 

Firewall is handled by AVG Internet Security

Is this issue due to the code in my application, desktop not being able to manage requests like a server machine, antivirus or a mix of the three?
If so, how can I set-up the server to reset automatically?

Thanks

UPDATE

It is a application where users write reports on files after reviewing information 

-Frequent sql requests for file data

-No images

-Some pages contain multiple sql queries that represent the page content

-Network has no internet connection

-Code does not make requests for external information from the internet

-All client machines run the application on Google Chrome web browser

Apache localhost not responding to clients until reset
