It's only this data structure that leaks, if I change it slightly it doesn't leak, so I'm guessing it's the garbage collector. ------------------------------------------------------------------------ [2006-07-20 15:38:39] joe at estara dot com Mike: Please just run this below script on your machine, and then use top, hit 'M' to sort by memory and apache will be the top memory user. hit the script 10 times and your machine will start swapping to death. This appears to be apache related: if the same script is hit, it doesn't leak MORE memory, it stays at the outrageously high level it got to the first time. <?php ini_set("memory_limit", "64M"); function make_arr() { for($i=0; $i<396768; $i++) $a[sprintf("%05d",$i)] = array(0 => "PHPLEAKS923889239823", 1 => "PHPLEAK2349082349898"); return $a; } for($i=0;$i<10;$i++) $zip[$i] = make_arr(); for($i=0;$i<10;$i++) preg_match("/asdfl/", $zip[$i]["00601"][0]); ?> ------------------------------------------------------------------------ [2006-07-20 15:23:40] [EMAIL PROTECTED] Not enough information was provided for us to be able to handle this bug.

Thank you for your interest in PHP. Any evidence like valgrind etc? The OS releases memory when it needs it. ------------------------------------------------------------------------ [2006-07-06 18:27:57] joe at estara dot com Arrays of arrays leak memory in many PHP versions. ------------------------------------------------------------------------ [2006-07-01 00:15:27] joe at estara dot com Here, fully contained version that will make a 131M leak in 12 lines. <?php ini_set("memory_limit", "64M"); function make_arr() { for($i=0; $i<396768; $i++) $a[sprintf("%05d",$i)] = array(0 => "PHPLEAKS923889239823", 1 => "PHPLEAK2349082349898"); return $a; } for($i=0;$i<10;$i++) $zip[$i] = make_arr(); for($i=0;$i<10;$i++) preg_match("/asdfl/", $zip[$i]["00601"][0]); ?> ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
