I'm running freeradius on  debien 5.0 system.
I have noticed that freeradius only fork one process whereas it's not running in single server mode:

ps aux | grep '^freerad.*\/usr\/sbin\/freeradius'
freerad   1930  1.6  3.9 833900 82072 ?        Ssl  Sep15  25:42 /usr/sbin/freeradius

my options for threads pool are set as below:

thread pool {
        start_servers = 5
        max_servers = 64
        min_spare_servers = 3
        max_spare_servers = 10
        max_requests_per_server = 0
}

I thought I should have 5 freeradius processes forked at startup...
Is there something wrong here?

regards
