ID: 42220 Updated by: jani@php.net Reported By: mv at binarysec dot com -Status: Open +Status: Feedback Bug Type: Scripting Engine problem Operating System: linux PHP Version: 5CVS-2007-08-06 (CVS) New Comment: You need to provide better information how we can reproduce this. If you don't even use APC why did you even mention it??! Some code with which it happens and such..it's not necessarily even any thread-safe issue.. Previous Comments: ------------------------------------------------------------------------ [2007-08-12 17:41:55] mv at binarysec dot com There is no php.ini defined, i used Apache 2.2.3 -worker- + PHP_5_2 as a module (cvs). In fact i have saw the problem 2 times on a core 2 duo and many times on my quad core which i used to develope. I use nikto & curl to load the server. Have fun ;) ------------------------------------------------------------------------ [2007-08-12 14:13:42] jani@php.net And you didn't mention anything about how you've configured PHP and under what webserver you're using it.. ------------------------------------------------------------------------ [2007-08-12 14:13:05] jani@php.net The question is: Do you get it at all when APC is NOT loaded? ------------------------------------------------------------------------ [2007-08-06 12:06:56] mv at binarysec dot com Description: ------------ Hi, I have a thread safe problem with the true global list_destructors, sometimes i got some messages like : <b>Warning</b>: Unknown list entry type in request shutdown (1882088036) in <b>Unknown</b> on line <b>0</b><br /> It happens very randomly i don't really know how to reproduce the code, but APC looks to help to get the error. I had a look at list_entry_destructor() zend_list.c +374 why does this function generate this error and it looks that list_destructors isn't thread safe. I **need** to fix that because sometimes you could get a blank page with APC. Reproduce code: --------------- none Expected result: ---------------- none Actual result: -------------- <b>Warning</b>: Unknown list entry type in request shutdown (1882088036) in <b>Unknown</b> on line <b>0</b><br /> ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42220&edit=1
