Repeated execution of provided script will lead to some serious memory leaks (200-500 MB per process). Image should be huge enough. I used this one: http://home.bsrealm.net/IMG_2466.JPG Test script: --------------- <?php header("Content-Type: text/plain"); ini_set('max_execution_time', 10); $st_tm = time(); $diff = 0; while (1){ $image = new \Imagick(realpath('./IMG_2466.JPG')); $image->thumbnailImage(64, 48, true, false); $image->clear; $image = null; if ((time() - $st_tm) > $diff) { $diff = (time() - $st_tm); echo "Waiting to Die " . date('h:i:s') . "\n"; flush(); } } ?> Expected result: ---------------- All memory should be freed after script is killed. Actual result: -------------- Memory is not freed. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74387&edit=1
