[users@httpd] how to prevent the apache main process from accepting the connection from remote host?

[sideslinder]

If the main proces accept the remote connection, the configuration as below
will fail to reboot the apache process.
<IfModule mpm_winnt_module>
    ThreadsPerChild        150
    MaxConnectionsPerChild   100
</IfModule>

So, when the max connection(the connection was accepted by the main
process) reached, Apache will not restart, and any other client can not
access the Apache web server.

Hope to find a solution. Thank you.
