AcceptEx() is a Microsoft WinSock v2 API that provides some performance
improvements over the use of the BSD style accept() API in certain
circumstances. Some popular Windows products, typically virus scanning
or virtual private network packages, have bugs that interfere with the
proper operation of AcceptEx(). If you encounter an error condition like:
[error] (730038)An operation was attempted on something that is not a
socket.: winnt_accept: AcceptEx failed. Attempting to recover.
you should use this directive to disable the use of AcceptEx().

> Well, that's really strange, because those servers are basically very clean. No software
firewall, antivirus, or something similar. Those are production servers, so they are really
running nothing else than MySQL, Apache and Tomcat... SP4 is installed as well.
