Why must clients exist when radius starts?

[Douglas Phillipson]

Is there a configuration option that will allow me to put a client IP in 
the clients file without the client actually existing yet?  It seems 
when radius starts, if a client doesn't exist the daemon dies.  I looked 
in the archives but I don't quite know what to query for.

Also is it the case that when the log is rolled, the daemon re-reads the 
config files and would die if it can't contact a client at this time?
