Description:
------------
We use PHP 5.3.14

Sometimes ajax post to a PHP page, results in $_SERVER content-length to be set 
correctly, but the $_POST does not have all data. I have also tested php://input 
to see if the data was received. But the data was truncated. This is NOT a file 
upload.

The data could be of 1000-5000 chars. But only 400-600 chars are received.

This is intermittent.

Could be similar to https://bugs.php.net/bug.php?id=22427

Expected result:
----------------
The post values submitted by ajax request should be available in $_POST.

Actual result:
--------------
The post value is truncated.

$_SERVER['Content-Length'] is set by the web server and tends to come directly 
from the Content-Length header the client sends. If the client aborts before 
sending all the data the web server is not going to adjust this value. This is 
quite normal. You can check the connection status to see if the client aborted 
mid-request on you. See http://php.net/manual/en/features.connection-handling.php
