Query on StartServers and ListenBackLog

["Arnab Ganguly" <aganguly01@xxxxxxxxx>]

Hi All,
I have some queries on the StartServers param.As it says "The StartServers directive sets the
    number of child server processes created on startup. As the number
    of processes is dynamically controlled depending on the load,
    there is usually little reason to adjust this parameter" from the Apache page.I wanted to know suppose I make the StartServers as 1.During the startup time only one active child process gets created.But after running it for a day or two a new daemon process gets launched apart from the other existing 
one.It would be nice if you can tell me as what point due to the load does Apache spawns another daemon?The value of ServerLimit I kept is one but still the behavior is same.

One more question I have is about the ListenBackLog.Is
 the request is always read from this queue or the queue comes into the picture only when the Idle thread count is zero?Suppose the ListenBackLog is full what would happen to the request received by Apache?

If Idle thread count is zero do still this ListenBackLog gets filled for the requests are coming and the request are read from this queue 
only.Looking forward for response.

Thanks and regards
