Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php When that option is turned on the output is being buffered in memory causing the memory problem you are seeing. Previous Comments: ------------------------------------------------------------------------ [2005-01-30 18:00:11] adyzah at hotmail dot com Yes, is set to 1. And indeed if i set it to 0 it works. But i am not sure if i can set it to 0 :( Btw: from my observations if i put memory limit 200M and try to download a 150M file, judging from the delayed response, seems that the php engine tries to buffer all content, which is abnormal. Session initialisation should have to affect headers and not content. Thanks, Adrian Zaharia ------------------------------------------------------------------------ [2005-01-30 17:11:57] [EMAIL PROTECTED] Do you have session.use_trans_sid enabled? ------------------------------------------------------------------------ [2005-01-30 12:10:31] adyzah at hotmail dot com Description: ------------ I am testing the following code that pushes a file to the browser (Linux + Apache 1.3 + PHP 4.3.10 but tested also under several other configs) !!!!!! Try it with a BIG test1.zip (e.g. 100M in size) Try it with wget http://server/test.php or a browser but the result is more accurate when using wget since in browsers could work if you already had a succesfull download of a smaller file. !!!!!! What i discovered is that if i keep the 2 session initialisation functions the script will work ONLY if the allocated memory in php.ini is greater than the size of the tested file. If i remove the session functions the script works fine even if the test1.zip file is very big (hundreds of Megs) Reproduce code: --------------- <?php session_save_path('/tmp'); session_start(); $sFileName = 'test1.zip'; $sFileDir = '/var/www/html/'; header("Content-Type: application/octet-stream"); header("Content-Disposition: attachment;filename=\"" . $sFileName . "\""); header("Content-Length: " . filesize($sFileDir . $sFileName)); header('Pragma: cache'); header('Cache-Control: public, must-revalidate, max-age=0'); header('Connection: close'); header('Expires: ' . date('r', time()+60*60)); header('Last-Modified: ' . date('r', time())); $oFp = fopen($sFileDir . $sFileName, "rb"); $iReadBufferSize = 512; while (!feof($oFp)) { echo fread ($oFp, $iReadBufferSize); } fclose ($oFp); exit; ?> Expected result: ---------------- The file should dowload via a browser or via wget Actual result: -------------- tail from apache error_log: Allowed memory size of 12582912 bytes exhausted (tried to allocate 10240 bytes) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=31763&edit=1
