[Serusers] Shutdown handling of SER

[Andreas Granig]

Hi,

I'm just curious about the way SER performs a shutdown. Is there a 
graceful shutdown handling? If so, what exactly is done?

IMHO a nice way would be to stop accepting new transactions (rejecting 
them with 301 for example to allow them to be resend to another server) 
but still accepting messages corresponding to ongoing transactions like 
100/180/200 responses and ACK requests. If there are no more incomplete 
transactions, the socket could be closed and the process could shut down.

Comments?
