Could you also send me your error.log?

You should do:

Make sure there is a core dump area with something like:

  CoreDumpDirectory /tmp

Make sure limits are set to dump core:

  ulimit -c unlimited

Restart and trigger the error.  A core file should be in the directory
you specified.

Then use gdb to get a backtrace:

gdb /path/to/httpd /path/to/core --batch --quiet \
  -ex "thread apply all bt full" > backtrace.log
