Stut, put this problem aside for a sec, and let me ask this - if I can produce an apache core-dump using vanilla apache, vanilla php (even with no extensions if you want) and a PHP script, you'll get someone to debug it? (I cannot promise a easily reproducable problem, just the core-dump, and a few hundred lines of script) FYI, I've tried that before, and the PHP developers are not interested and/or they do not work with core dumps. I still maintain it is exceptionally poor show by php to let user code produce segfaults in apache. Here's a brief excerpt from a recent apache error-log: [Thu Aug 30 12:31:20 2007] [notice] child pid 18836 exit signal Segmentation fault (11) [Fri Sep 07 10:09:22 2007] [notice] child pid 2634 exit signal Segmentation fault (11) [Fri Sep 07 12:25:07 2007] [notice] child pid 18835 exit signal Segmentation fault (11) [Fri Sep 07 12:26:10 2007] [notice] child pid 18834 exit signal Segmentation fault (11) [Fri Sep 07 12:26:48 2007] [notice] child pid 21729 exit signal Segmentation fault (11) [Fri Sep 07 17:18:55 2007] [notice] child pid 18647 exit signal Segmentation fault (11) [Fri Sep 07 21:04:45 2007] [notice] child pid 20318 exit signal Segmentation fault (11) [Fri Sep 07 21:04:54 2007] [notice] child pid 18403 exit signal Segmentation fault (11) [Sun Sep 09 17:43:26 2007] [notice] child pid 18826 exit signal Segmentation fault (11) [Sun Sep 09 17:43:53 2007] [notice] child pid 18827 exit signal Segmentation fault (11) [Sun Sep 09 17:44:10 2007] [notice] child pid 18825 exit signal Segmentation fault (11) [Sun Sep 09 17:45:08 2007] [notice] child pid 18447 exit signal Segmentation fault (11) [Sun Sep 09 17:45:24 2007] [notice] child pid 18785 exit signal Segmentation fault (11) [Sun Sep 09 17:46:06 2007] [notice] child pid 25399 exit signal Segmentation fault (11) [Mon Sep 10 15:18:52 2007] [notice] child pid 28626 exit signal Segmentation fault (11) [Mon Sep 10 15:19:22 2007] [notice] child pid 28608 exit signal Segmentation fault (11) [Mon Sep 10 15:20:10 2007] [notice] child pid 28856 exit signal Segmentation fault (11) [Mon Sep 10 15:20:12 2007] [notice] child pid 28605 exit signal Segmentation fault (11) [Mon Sep 10 15:23:07 2007] [notice] child pid 28607 exit signal Segmentation fault (11) [Mon Sep 10 18:31:39 2007] [notice] child pid 20378 exit signal Segmentation fault (11) These were all caused by PHP user code with PHP5 and apache22. /Per Jessen, Zürich
