When running PHP 4.3.4 (also 4.3.2) in FastCGI mode, the http upload of files occasionally results on "Page Cannot Be Displayed".

Some comments:

1. The SAME file sometimes is uploaded successfully and sometimes is not. So, no problems with MAX_FILE_SIZE (HTML script) or UPLOAD_MAX_FILESIZE, POST_MAX_SIZE (PHP.INI) settings.

2. No problems with plain/text files uploads. These intermittent problems seem to occur only with binary files.

3. On a manual test, in 60 seconds, the same requisition failed 8 times and succeeded other 4.

Reproduce code:
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="20971520">
<input name="userfile" type="file"><br>
<input type="submit" value="Send files">

if(move_uploaded_file($_FILES['userfile']['tmp_name'], "uploaded/".$_FILES['userfile']['name'])) {
    echo "SUCCESSFULL";
} else {
    echo "ERROR<br>";

The problem persists.
This time I was able to identify that the error occurs more often when the file size is over 50KB.
