The number of open files just keeps increasing. For some reason PHP 4.4.7 don't have this behavior, that is, apache keeps the number of open files somewhat constant when PHP is not running. For phpMyAdmin the first entries of lsof looks like: # lsof -u www | grep "\.php" | head httpd 678 www 6r REG 14,2 26700 915904 /Users/data/htdocs/mysql/libraries/common.inc.php httpd 678 www 7r REG 14,2 18504 915886 /Users/data/htdocs/mysql/libraries/core.lib.php httpd 678 www 8r REG 14,2 2063 915950 /Users/data/htdocs/mysql/libraries/sanitizing.lib.php httpd 678 www 9r REG 14,2 9447 915968 /Users/data/htdocs/mysql/libraries/Theme.class.php httpd 678 www 10r REG 14,2 10571 915906 /Users/data/htdocs/mysql/libraries/Theme_Manager.class.php httpd 678 www 11r REG 14,2 9447 915968 /Users/data/htdocs/mysql/libraries/Theme.class.php httpd 678 www 12r REG 14,2 33846 915974 /Users/data/htdocs/mysql/libraries/Config.class.php httpd 678 www 13r REG 14,2 44257 915868 /Users/data/htdocs/mysql/libraries/Table.class.php httpd 678 www 14r REG 14,2 79607 915957 /Users/data/htdocs/mysql/libraries/common.lib.php httpd 678 www 18r REG 14,2 1919 915824 /Users/data/htdocs/mysql/libraries/js_escape.lib.php ------------------------------------------------------------------------ [2007-11-29 16:03:43] marcus dot mueller at grintsch dot com As I stated above we have this issue on two Linux boxes with self-compiled PHP binaries.
