What kind of server API are you using and is it threaded or not?

sorry, wrong code. here's the code
$tid = isset( $_GET['tid'] ) ? $_GET['tid'] : "";
$file = "/data/".$tid.".txt";
if(file_exists($file)) {
echo "1";
} else {
echo "0";
}

Description:
------------
is_file() or file_exists() returning false on existing file.
the script is executed about 8x per second and checking a file in a
directory filled with 5000 to 30000 files.
for 344000 execution, it fails about 2000 times.
no change on php.ini
Reproduce code:
---------------
$tid = isset( $_GET['tid'] ) ? $_GET['tid'] : "";
$file = "/data/".$tid.".txt";
if(file_exists()) {
echo "1";
} else {
echo "0";
}
Expected result:
----------------
for 344000 execution, it should producing 1 for 344000 times.
Actual result:
--------------
less than 344000 times of 1 echoed.
