rlm_perl does not honor start_servers?

[Igor Novgorodov]

Okay, thank you very much for the info.

I'll take a look on the rlm_perl code and maybe come up with a patch...

In the meantime it seems that i have to add some logic to the init 
script that will:
1. Block RADIUS port in iptables to not overwhelm the daemon
2. Start FreeRADIUS
3. Warm the server up with radclient
4. Unblock port and let the main traffic flow in
