Fixed  Memory leak in downloading file up to 40 M

php.ini file is ok
upload 50M file ok
but download doesn't work

<b>Fatal error</b>:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 42438428 bytes) in <b>public_html/board/library/Zend/Controller/Response/Abstract.php</b> on line <b>585</b><br />
This error happened with any php.ini config
