Apache 2.0.X does not work with McAfee VirusScan on Windows 2000/XP 
Windows 98/Millennium systems. McAfee is aware of the problem but I have not 
been able to find a report that describes this within Apache's bug reports, 
but there may be related bug found by searching for AcceptEx.

The symptom is a spinning McAfee process that effectively eats up all CPU 
available time. No connections may be made to Apache, neither from onboard 
(127.0.0.1 or localhost) or external. The error log states (repeatedly):

child.c(547): (OS 10038)An operation was attempted on something that is not a 
socket.  : winnt_accept: AcceptEx failed due to early client disconnect. 
Reallocate the accept socket and try again.

in conjunction with other applications, which include a Layered Service

successfully. Those that are known to conflict with the McAfee LSP are listed 
below:
