Well than it is also better to push the output into the nirvana as with timeout
ping 127.0.0.1 -n 30 > nul |

I had an idea to use php function sleep instead of ping if there is no timeout since the script already uses php.
One more question, why don't you use -k restart? |

php use lot of memory eq from 4 to event 8mb
sleep use kb not MB
but is possible this is concept you can modified as well

In my cfg is better to kill php-cgi and kill Apache instance and start again
I had 100000 request until php-cgi.exe [ wincache not flush memory ] will be restart, so if Apache fail better is to stop, kill and run again
Maybe a some modification
TASKKILL /F /IM php-cgi.exe
%PATH_TO_HTTPD%\httpd -n Apache -k stop
TASKKILL /F /IM httpd.exe
%PATH_TO_HTTPD%\httpd -n Apache -k start
###
To
###
TASKKILL /F /IM php-cgi.exe
%PATH_TO_HTTPD%\httpd -n Apache -k restart
##
timeout /t 5 /nobreak > NUL
Check is Apache still ruining [ php script and some eq request to graphic ] if not do old code witch - stop and -start
----------
of course -restart in you situation will be better idea eq all request to apache still response not 3 - 4 second offline |

Well if there is a need for high accessibility I use a load balancer where I can restart the backend servers one after another. With enough RAM it is also possile to do that on one server apaches listing on different ports.
of cause ideal it is to have two loadbalancers. One in hot standby the other serving the requests. Each with a bunch of backend server behind with real hardware. |
