What more information do you need? As already mentioned:
1) create a test.htm file (in your top level directory that localhost
points to) with the following content:
<html>
<head>
<link rel="stylesheet" href="/systeem/style/style.css">
<title> V.V. De Meern</title>
<meta name="description" content="V.V. De Meern">
<meta name="robots" content="index,follow">
<script src="/beheer/include/header.js"> </script>
</head>
<body>
<script src="menu.js"> </script>
<a href="menu.html"> </a>
<h1> Home pagina A1</h1>
<p> <img src="a1.jpg" border="0" alt="" /></p>

<h1> Leiders</h1>
<p> John Dunsbergen, Joost Satink, Lex van der Woude</p>
<script src="/beheer/include/footer.js"> </script>
</body>
</html>
2) Create a test.php file containing:
<?php
echo '<pre> ';
for ($i=1;;$i++)
{ echo $i."\n";
flush();ob_flush();
$contents = file_get_contents('http://localhost/test.htm');
}
?>
3) Run the test.php file from your browser. It display 1, 2, 3, 4, etc
and after 202 iterations it hangs because the Apache server has
crashed.
PS. The problem also occurs if you use fopen(), fgets(), fclose()
instead of file_get_contents.

Description:
------------
Apache crashes if a lot of file_get_contents are done. The Apache
error.log only contains this (I guess this just confirms that the Apache
server has crashed and no longer responds): [Fri May 09 12:15:04 2008]
[error] [client 192.168.0.1] PHP Warning:
file_get_contents(http://localhost/test.htm) [<a
href='function.file-get-contents'> function.file-get-contents</a>]:
failed to open stream: A connection attempt failed because the connected
party did not properly respond after a period of time, or established
connection failed because connected host has failed to respond.\r\n in
C:\\Andre\\Apache\\test.php on line 6
Reproduce code:
---------------
The following PHP script reproduces the problem:
<?php
echo '<pre> ';
for ($i=1;;$i++)
{ echo $i."\n";
flush();ob_flush();
$contents = file_get_contents('http://localhost/test.htm');
}
?>
After 203 iterations the Apache server crashes. The result is the same
whether localhost or IP address is used.
The problem depends on the contents of the test.htm file. If it only
contains
<html>
<body>
</body>
</html>
the script runs until it reaches the max execution time.
The test.htm that reproduces the problem contains:
<html>
<head>
<link rel="stylesheet" href="/systeem/style/style.css">
<title> V.V. De Meern</title>
<meta name="description" content="V.V. De Meern">
<meta name="robots" content="index,follow">
<script src="/beheer/include/header.js"> </script>
</head>
<body>
<script src="menu.js"> </script>
<a href="menu.html"> </a>
<h1> Home pagina A1</h1>
<p> <img src="a1.jpg" border="0" alt="" /></p>

<h1> Leiders</h1>
<p> John Dunsbergen, Joost Satink, Lex van der Woude</p>
<script src="/beheer/include/footer.js"> </script>
</body>
</html>
Expected result:
----------------
Run until max execution time exceeded.
Actual result:
--------------
Crashed beforehand.
