Description:
------------
a log-file has reached its maxmimum file size allowed by the 
operation and file system.

Appending further additional byte to this file ends the php and apache process without any message. Nothing in error_log and console output.

Script procession simply stops.


Reproduce code:
---------------
  function append_to_file($aFilename, $aData)
  {
    clearstatcache();
    
      $fh = fopen($aFilename, 'a');
      if ($fh === false) {
        return (-1);
      }
      $result = fwrite($fh, $aData);
      fclose($fh);

    return ($result);
  }


Expected result:
----------------
Error Message or Warning and script continues to execute

tested with
php 5.1.2 and 5.0.5


Actual result:
--------------
script stopped/ended without any notice
