check active threads

freeradius 1.4 on CentOS 4.4 How can I verify the number of threads? I only see one process with

ps aux | grep radiusd I could have sworn I used to see each thread with 0.9 and I am concerned that the threads are not starting correctly as defined in radiusd.conf: thread pool { start_servers = 5 max_servers = 32 min_spare_servers = 3 max_spare_servers = 10 max_requests_per_server = 0 }
