Description: ------------ System - mod_fastcgi. 1 process x 35 child php threads - PHP 5.3.1 dotdeb package - Mysqlnd Active Links increases throught the running of the server, for one it is greater than the number of threads so there obviously is a leak. PHPInfo: http://thewarezscene.org/phpinfo.php Reproduce code: --------------- <? $db = mysqi_connect(....); echo 'test'; mysqli_close($db); ?> Open script a few thousand times and take a look at phpinfo() Expected result: ---------------- Active Links = 0; Actual result: -------------- Active Links = XXXX; http://thewarezscene.org/phpinfo.php ^ I have to kill all processes every 3 hours to keep the number down and hence the memory usage.

Ok, I have some code that reproduces this bug I believe. <?php for($i=0;$i<=100000;$i++){ $m = mysqli_init(); mysqli_real_connect($m,'localhost','root','passwordmysql'); $m = mysqli_close($m); unset($m); if(($i%1000)===0){ echo "Memory consumption after $i iterations is " . memory_get_usage() . "<br /><br />"; flush(); } } die(); ?> Result: Memory consumption after 0 iterations is 660120 Memory consumption after 1000 iterations is 852600 Memory consumption after 2000 iterations is 1044832
