Please try using this CVS snapshot: http://snaps.php.net/php5.1-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.1-win32-latest.zip Previous Comments: ------------------------------------------------------------------------ [2005-12-13 09:05:35] vovik at getart dot ru I'll try to explain the issue more clear. If one php script (heavy.php) tried to allocate memory more than memory_limit php.ini setting it will exited with fatal error ("Allowed memory size exhausted"). In apache access_log it reports highest memory value used (close to php memory_limit). Another script (light.php), which allocate small amount of memory, executed after. And it will report in access_log the same high value as heavy.php. Obviously, it happens only if light.php executed on the same apache child. If i try to call memory_get_usage() in light.php - it reports normal low value. But in access_log it still the same as heavy.php. All following requests to this apache child reports one value for memory peak in access_log. As result, access_log looks like this: "GET /heavy.php HTTP/1.1" 200 - php(806944) "GET /light.php HTTP/1.1" 200 16 php(806944) "GET /something.php HTTP/1.1" 200 160 php(806944) ... and so on ... It looks like php keeps allocated memory peak and not drops it after fatal error due to memory limitation. ------------------------------------------------------------------------ [2005-12-12 18:28:08] [EMAIL PROTECTED] 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 Memory isn't _really_ freed but during shutdown. ------------------------------------------------------------------------ [2005-12-12 14:51:17] vovik at getart dot ru Description: ------------ I using 'LogFormat "%h %l %u %t \"%r\" %>s %b php(%{mod_php_memory_usage}n)" common' in httpd.conf for logging php memory usage. If php script exited on fatal error due to memory limitation, %{mod_php_memory_usage}n keeps high value for all following requests to this apache child. Reproduce code: --------------- if (@$_GET["test"] == 1) { print "Allocated: ".memory_get_usage(); } else { ini_set("memory_limit", 1048576 * 100); // 100K // PHP exited in file_get_contents with message: // PHP Fatal error: Allowed memory size of 104857600 bytes exhausted $bigfile = file_get_contents("/etc/termcap"); // this file is about 800K on my host } First, run this script without parameter, next with ?test=1. Check apache log then. Expected result: ---------------- [12/Dec/2005:13:28:47 +0000] "GET /test.php HTTP/1.1" 200 - php(806944) [12/Dec/2005:13:28:57 +0000] "GET /test.php?test=1 HTTP/1.1" 200 16 php(*****) // not the same as previous, should be much lower Actual result: -------------- [12/Dec/2005:13:28:47 +0000] "GET /test.php HTTP/1.1" 200 - php(806944) [12/Dec/2005:13:28:57 +0000] "GET /test.php?test=1 HTTP/1.1" 200 16 php(806944) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=35646&edit=1
