Sorry for the delay.
I need you to run dhcpd with valgrind.

1) install dhcp-debuginfo package like this:
   yum --enablerepo=updates-debuginfo install dhcp-debuginfo
2) install valgrind:
   yum install valgrind
3) run dhcpd with valgrind:
   valgrind -v --tool=memcheck --log-file=valgrind.log dhcpd -d
4) Perform any actions necessary to reproduce the crash.
5) Attach valgrind.log to this bug report

Thanks
