Re: Apache segmentation faults

Is there any special apache/php compile option needed to generate core files on linux? I have seen few segfaults and i have set CoreDumpDirectory to /tmp/httpd.core which has correct permissions but no core file gets generated. Are core files generated only when apache parent process segfaults?
