With a little luck, you can get apache to leave you a core file that can later be loaded in gdb to find the problem. See: http://httpd.apache.org/docs-2.0/mod/mpm_common.html#coredumpdirectory Another alternative is mod_log_forensic: http://httpd.apache.org/docs-2.0/mod/mod_log_forensic.html which is designed to isolate requests that cause a crash.
