Indy: closing a connection on servers when all connectiosn closed, and timeouts

Hello,
     Hopefully two not too hard questions. I have the latest stable version of Indy. I am probably just looking at the wrong properties.

1) how do I set timeouts on servers, so that if there is no data flowing, the connection is closed after x amount of time.
2) How do I test to see if there are any live connections to the servers, and if there are not, then stop the server.

ftpserver.Threads.LockList.Count = 0
appears to work well the first time I  check it, but then I set up a timer, then inside the timer I call

if ftps then begin
  try
    if ftpserver.active  and (ftpserver.Threads.LockList.Count = 0) then begin //the program dies here
      ftpserver.Active := false;
        ftps := false;
      end else good := false;
  except
    good := false;
  end;
  end;

I have an antifreeze component on the form, and the problem happens both when I run from within the IDE and externally.

when the program dies, it appears to be running, I can not trace into the line.

Thanks in advance
