New Comment:
While I can reproduce the problem, I couldn't spot the error at first
sight, because the code is very complex (and without valgrind even
worst..)

Description:
------------
I launch processes in a script and put stout in file
after more than 2000 processes and can't open a new one and have this
message.
It's similar with 30743 bit it uses 2 pipes for $fileDescriptors and in
this case it's a pipe and a file
Reproduce code:
---------------
<?
set_time_limit(6000);
$i=0;
mkdir(test);
while(1)
{
$i++;
echo("-$i--\n");
invoke($i);
}
function invoke($i)
{
$commandLine = "echo hello";
$fileDescriptors = array(
1 => array("pipe", "r"),
2 => array("file", "test/$i.txt","w")
);
$pipes = array();
$processHandle = proc_open($commandLine,$fileDescriptors, $pipes);
if (is_resource($processHandle))
{
fclose($pipes[1]);
proc_close($processHandle);
}
}
Expected result:
----------------
Open a new one
Actual result:
--------------
<b>Warning</b>: proc_open(test/2587.txt): failed to open stream: Too
many open files in <b>E:\cotcot\leak.php</b> on line <b>24</b><br />
