Apache connection was reset while the page was loading on windows 2008 server

I'm running a php script in windows 2008 server using xampp server, the script works normaly until I check some pages,it start loading I get this error in firefox :

The connection to the server was reset while the page was loading.

The site could be temporarily unavailable or too busy. Try again in a
few moments. If you are unable to load any pages, check your
computer's network connection. If your computer or network is
protected by a firewall or proxy, make sure that Firefox is permitted
to access the Web

.

When I check the php logs I get nothing, in apache logs I always find this after getting the problem:

I disabled the firewall, I change the port, I increase memory limit, without any result.
I do a backup of the script and I moved it to my laptop running with windows 7, the problem disapear and the script sart working normaly.

So is this problem causes by apache? and how I can fix it?

After many tests, I found that happens only in firefox browser and it's works normaly in google chrome, I cleared all cache and history in firefox but it's not working.I don't know what is the problem exactly but I'm woking now with chrome and I ignored firefox.Any suggestion will be appreciated.
