Apache (php) crashes when calling 2 or more php files at the same time

Question

I need to load multiple files from a database and I am using php to do it.

I am using windows 7 64 bits and xampp and uniserver as servers (xampp 1.8.3-4 VC11 and uniserver XI 11.3.1). Both crashes when I load at the exact same time two php files (they can be the same file with different get variables or different files). I tried with an older version of xampp but happens the same problem.

EDIT: I noticed that it only happens using the browser palemoon (I am using the version 24.7.1 x64). Chrome, Opera and Firefox works well. I don't understand why.

To reproduce it I only need to create a html file index.html with this content:

<!doctype html>
<html>
<head>
    <link rel="stylesheet" href="a.php"/>
    <link rel="stylesheet" href="b.php"/>
</head>
</html>

Now, create two blank files, one called a.php and the other b.php (it doesn't matter what it is written in them)

Lastly open the html on a browser and do ctrl-f5 until apache crashes.

The only thing apache logs about this is

I found this bug report but the last entry is from 2004 so I am wondering if this problem is a bug and, if it is, is the same bug: https://bugs.php.net/bug.php?id=25570

EDIT: Using this C# makes the server crash sometimes

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;

class MainClass
{
    public static void Main (string[] args)
    {
        IPAddress ipAddress = Array.FindAll(
            Dns.GetHostEntry("127.0.0.1").AddressList,
            a => a.AddressFamily == AddressFamily.InterNetwork)[0];
        IPEndPoint remoteEP = new IPEndPoint(ipAddress,80);

        Socket sender = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp );

        string request = "GET /a.php HTTP/1.1\r\n" + 
            "Host: 127.0.0.1\r\n" +
            "\r\n";

        sender.Connect(remoteEP);

        sender.Send (Encoding.UTF8.GetBytes (request));
        sender.Send (Encoding.UTF8.GetBytes (request));

        byte[] buffer = new byte[4096];
        int nBytes = 0;
        try {
            while ((nBytes = sender.Receive(buffer,4096, SocketFlags.None)) > 0)
            {
                // From byte array to string
                string s = Encoding.UTF8.GetString(buffer, 0, nBytes);
                Console.WriteLine(s);
            }
        } catch (SocketException e) {
            Console.WriteLine("error {0}", e.ErrorCode);
        }

        Console.WriteLine("\nPress a key...");
        Console.ReadKey();

    }
}

EDIT: I am using Connection: Close on the windows xampp server to elude the problem. My linux vps works perfectly, it only happens on the windows server.

I dont exactly understand your question, but I think this is what you mean. You can't use <link rel="stylesheet" /> to include a php file.

In order to include php code, you would have to do the following:

<!doctype html>
<html>
    <head>
       <!-- <link rel="stylesheet" href="a.php"/>
       <link rel="stylesheet" href="b.php"/> -->
    </head>
<?php

 require "a.php";
 require "b.php";

?>
</html>
