TYPO3 Core

When trying to download a large file (in my case a mp4 file) via FileDumpEID.php i get an out of memory error. The file is sent by the method dumpFileContents in class TYPO3\CMS\Core\Resource\Driver\LocalDriver. According to PHP manual the method readfile will not present any memory issues when output buffering is off, so i checked ob_get_level() in TYPO3\CMS\Core\Resource\ResourceStorage->dumpFileContents and for any reason it was 3.
Maybe it would be a good idea to disable output buffering before using readfile().

@public function dumpFileContents(FileInterface $file, $asDownload = FALSE, $alternativeFilename = NULL) {

[...]

while (ob_get_level() > 0) {
        ob_end_clean();
    }
    $this->driver->dumpFileContents($file->getIdentifier());

}@
