I don’t know if no one saw it, or no
one can help, but I’ll try one more time, this is honestly my last hope
and im not sure what else to do Im having trouble debugging a segmentation fault, the server
is only running a phpAdsNew ads server. The system: Dual opteron box running gentoo 2.6 kernel Apache 2.0.58 PHP 5.1.4 When we hit our peak hours is when the seg faults start
occurring: [Tue Jul 25 13:09:32 2006] [notice] child pid 20868 exit
signal Segmentation fault (11) [Tue Jul 25 13:09:32 2006] [notice] child pid 20877 exit
signal Segmentation fault (11) [Tue Jul 25 13:09:32 2006] [notice] child pid 20895 exit

signal Segmentation fault (11) [Tue Jul 25 13:09:34 2006] [notice] child pid 20903 exit
signal Segmentation fault (11) This will happen every 5-10 minutes in blocks like that. At first I thought it was a ram issue, but when I moved it
to another web server running apache 2.0.58/php5.0.4 the same thing happens.
I’ve attempted to setup a core dump directory using the CoreDumpDirectory
directive, the directory is owned by the apache user and “ulimit –c unlimited” was run before
starting apache, however nothing is ever outputted. I did read
that this has something to do with apache starting as root and then switching
to the correct user, but with kernel 2.4+ it should still output, maybe im
wrong. Next I tried to setup mod_whatkilledus (http://people.apache.org/~trawick/mod_whatkilledus.c),
I compiled apache with –enable-exception-hook, and I have the
EnableExceptionHook directive on and the module is loaded, however as you can
see from my log output mod_whatkilledus is not doing anything. Is there
something im missing to make both of these work? Any help would be appreciated
