radiusd -X On First Boot

I am running RHEL 5.3 and FreeRADIUS Version 2.1.8. When I install freeradius and attempt to start it for the first time using the /etc/init.d/radiusd start script it always fails (only right after freeradius is installed), once i run freeradius with -X (in debug mode) it creates all the keys and such then I can cntrl + c and start free radius from that point forward using the init script... my question is why do I have to do this? Is there anyway around this? Thanks, Brian Carpio
