Hi,

I don't know if it's a perl child.

I have followed the apache core dump instruction from http://httpd.apache.org/dev/debugging.html#crashes

I got the core dump

dell:~ # gdb httpd2 /tmp/apache-cores/core

(gdb) bt full #0 0x00007f43f5131320 in apr_palloc () from /usr/lib64/libapr-1.so.0 No symbol table info available. #1 0x00007f43f5129713 in apr_table_make () from /usr/lib64/libapr-1.so.0 No symbol table info available. #2 0x00007f43f5a173bd in ap_scan_script_header_err_core () No symbol table info available. #3 0x00007f43f5a1795e in ap_scan_script_header_err_strs () No symbol table info available. +#4 0x00007f43f002479a in modperl_cgi_header_parse () from /usr/lib64/apache2/mod_perl.so No symbol table info available. #5 0x00007f43ee639683 in XS_Apache2__RequestRec_send_cgi_header () fr +om /usr/lib/perl5/vendor_perl/5.14.2/x86_64-linux-thread-multi/auto/A +pache2/Response/Response.so No symbol table info available. #6 0x00007f43efd3bc8f in Perl_pp_entersub () from /usr/lib/perl5/5.14.2/x86_64-linux-thread-multi/CORE/libperl.so No symbol table info available. #7 0x00007f43efd33126 in Perl_runops_standard () from /usr/lib/perl5/5.14.2/x86_64-linux-thread-multi/CORE/libperl.so No symbol table info available. #8 0x00007f43efcceede in Perl_call_sv () from /usr/lib/perl5/5.14.2/x86_64-linux-thread-multi/CORE/libperl.so No symbol table info available. #9 0x00007f43f0019725 in modperl_callback () from /usr/lib64/apache2/mod_perl.so No symbol table info available. #10 0x00007f43f0019f5c in modperl_callback_run_handlers () from /usr/lib64/apache2/mod_perl. +so No symbol table info available. #11 0x00007f43f001a49f in modperl_callback_per_dir () from /usr/lib64/apache2/mod_perl.so No symbol table info available. #12 0x00007f43f001490b in ??

But I still have no clue on what's wrong from the message, anyway to have a more clear one ? Thanks
