+ Child: Encountered too many AcceptEx faults accepting client connections.<br />
+ winnt_mpm: falling back to 'AcceptFilter none'.

+ <p>The MPM falls back to a safer implementation, but some client requests
+ were not processed correctly. In order to avoid this error, use
+ <directive module="core">AcceptFilter</directive> with accept filter
+ <code>none</code>. <em>In Apache httpd 2.0 and 2.2,
+ <directive>Win32DisableAcceptEx</directive> was used for this purpose.</em></p>
