  That's possible.

$ man radiusd

  Read the description of the first option.

  Because it makes more sense there.  This lets the server automatically
balance load across threads... independent of which virtual server is
being used.

  If you want to limit the number of server threads, run multiple
configurations, and multiple server processes.

  Yes.  You check the configuration before starting or re-starting the
server.  Don't re-start the server if the configuration is wrong

  No.  If resource limits are a problem, you should buy another machine.

  Realistically, resource limits won't be a problem on normal hardware.

  Yes.  See "man radiusd".  Look at the "-n" parameter.  You can do
*exactly* that.
