[Serusers] SER initialization/main loop queries

Hi I am going through the SER code. Can somebody please confirm if my understanding is correct in the following things happening during initialization time? 1. Use of "children" in cfg file: SER will fork a process for the IP interface specified; if not then one process each for all the IP addresses in the system. This it will do for TCP as well as UDP as well as TLS, means separate processes for each. Does "children" mean that how many processes you want to fork for each IP interface (or a socket) on which SER is listening? So depending on number of children, there will be multiple forked processes for each IP address/port. 2. If four children are forked for one process, then which one actually receives from socket as all four will be listening on same IP address/port? Is it that some list is maintained and at one time only the process at head node of list calls recvfrom()? After it receives and processes the incoming request, it is put to tail of list. 3. Why is the suggested "children" value 4? Regards, Gaurav Kansal
