最近在使用PHP5.6+Apache2.4,搭建开发环境;在实际的开发过程中发现http请求一致处于挂起状态,于是重启(net start/stop)Apache2.4服务,然后再访问问题得到了解决,但是过一会,平凡的打开页面又出现问题,通过查看web服务器的日志,发现报很多"指定的网络名不再可用"的错误:
[Thu Nov 20 14:07:43.151780 2014] [mpm_winnt:warn] [pid 8752:tid 1132] (OS 64)指定的网络名不再可用。 : AH00341: winnt_accept: Asynchronous AcceptEx failed. [Thu Nov 20 14:07:43.152781 2014] [mpm_winnt:warn] [pid 8752:tid 1132] (OS 64)指定的网络名不再可用。 : AH00341: winnt_accept: Asynchronous AcceptEx failed.

在网上找各种资料,都是说在httpd.conf文件中添加 Win32DisableAcceptEx 标记:
<IfModule mpm_winnt.c> ThreadsPerChild 150 MaxRequestsPerChild 10000 Win32DisableAcceptEx </IfModule>
配置之后问题依然未得到解决,最终查看Apache的手册(PS:查看最新的Apache2.4的手册),看到官方的如下解释:
The default values on Windows are:
AcceptFilter http dataAcceptFilter https data
Window‘s mpm_winnt interprets the AcceptFilter to toggle the AcceptEx() API, and does not
support http protocol buffering. There are two values which utilize the Windows
AcceptEx() API and will recycle network sockets between connections.
data
waits until data has been transmitted as documented above, and
the initial data buffer and network endpoint addresses are all retrieved from
the single AcceptEx() invocation. connect
will use the AcceptEx()
API, also retrieve the network endpoint addresses, but like none
the connect
option does not wait for the initial data
transmission.
On Windows, none
uses accept() rather than AcceptEx() and will
not recycle sockets between connections. This is useful for network adapters
with broken driver support, as well as some virtual network providers such as
vpn drivers, or spam, virus or spyware filters.
在配置文件中添加如下信息:
AcceptFilter http none AcceptFilter https none
