FreeRADIUS starts in seconds. I have restarted FreeRADIUS in very large production environments without a problem. If you are concerned about availability, use multiple FreeRADIUS servers and/or a load balancer (F5, Cisco, lvs, etc.).

Is this fix available now ? (freeradius server to read the change in nas-table without restart)

Thanks.
