Expected and Actual results fields are to be switched places. ------------------------------------------------------------------------ [2007-05-16 17:54:24] eth at ethaniel dot com Description: ------------ I run a image thumbnail service on my server, it runs under priority of +11. It has a memory limit set to 520M. On some images it exits with "Allowed memory size of 545259520 bytes exhausted" when I do imagecreatetruecolor(500,375). Memory usage details below. Reproduce code: --------------- if ($photo_id==2348804) error_log(memory_get_usage()." - $newX - $newY"); $newImg = ImageCreateTrueColor($newX, $newY); if ($photo_id==2348804) error_log(memory_get_usage()." - $newX - $newY"); Expected result: ---------------- following entry in error log [16-May-2007 19:10:27] 6451636 - 500 - 375 [16-May-2007 18:34:24] PHP Fatal error: Allowed memory size of 545259520 bytes exhausted (tried to allocate 2000 bytes) in /data1/albums/retreive.php3 on line 427 Actual result: -------------- I checked the memory usage right before imagecreatetruecolor and it was at 6.4M. The memory limit was set to 512M, script run under nice +11. It crashes on imagecreatetruecolor. But when I set the memory limit to 10000M it works ok and the code above returns. [16-May-2007 19:10:27] 6451636 500 - 375 [16-May-2007 19:10:27] 7405476 500 - 375 As you can see, the real memory usage raised only about 1MB instead of hitting the upper limit of 500MB. This happened only on some images. Don't know why. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41411&edit=1
