Apache on a production server of mine is seg faulting intermittently. I have enabled core dump option in apache configuration and have several dumped core files. Unfortunately, since it is a production server, apache or the loaded modules are not compiled with debug symbols. From what I understand, gdb cannot do much without debug symbols.
Can I at least find out which module is causing the seg fault, without debug symbols? If so, how?
Following is the output from a gdb backtrace
(gdb) bt full

Does this mean that /lib/ld-linux.so.2 is causing the seg fault?
