#28131 [Opn->Bgs]: Scripts can't consume more than 64MB on Windows XP/2000

ID: 28131 Updated by: wez@php.net Reported By: webmaster at macway dot com -Status: Open +Status: Bogus Bug Type: Reproducible crash Operating System: Windows 2000 PHP Version: 4.3.4 New Comment: Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. My 512MB laptop running XP will allocate 800MB (probably as much as the page file size, if I pushed it). C:\php4>php -r "$x = str_repeat('*', 128 * 1024 * 1024); echo 'Done';" Done C:\php4>php -r "$x = str_repeat('*', 400 * 1024 * 1024); echo 'Done';" Done C:\php4>php -r "$x = str_repeat('*', 600 * 1024 * 1024); echo 'Done';" Done C:\php4>php -r "$x = str_repeat('*', 800 * 1024 * 1024); echo 'Done';" Done C:\php4>php -r "$x = str_repeat('*', 1280 * 1024 * 1024); echo 'Done';" FATAL: emalloc(): Unable to allocate 1342177281 bytes It works fine; no crashes. You must have something wrong with your configuration; check your memory_limit and error_reporting settings and talk to someone on a support channel to discover the reason that you have problems with this.

It is reproductible. I've redonne some tests and it appears that the web server is nit the issue (launching the php.exe without any webserver exhibits the problem). I've you have 4 different variables, then the max size of each will be 64/4 = 16MB of ram max. That means the total ram consumed by the script has to be lower than 64MB ------------------------------------------------------------------------ [2004-04-26 12:02:02] wez@php.net We don't support third party PHP distributions. Please give the feedback we requested. ------------------------------------------------------------------------ [2004-04-26 10:22:53] webmaster at macway dot com I reproduced the bug using easyphp 1.7 on a windows xp machine. It crashes apache ! ------------------------------------------------------------------------ [2004-04-24 12:24:16] derick@php.net Upgrade apache from 1.3.9 to 1.3.29 first, then see if the problem persists. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
