doveadm proxy list

[Claus]

Hi,

i have configured my dovecot-proxy with "shutdown_clients = no" and 
"service_count = 1" for a "default_process_limit = 5000" and 
"default_client_limit = 25000".
I don't know if this is a prefered setup for so many users/concurrent 
sessions but so i can reload my dovecot without disconnecting all sessions.
The main problem are pop3 sessions - if i kill them, the mailbox remains 
locked and the client gets an error.

Back to my problem:
If i reload dovecot the "doveadm proxy list" shows me the list of the 
new processes.
Is there any possibility to see the stats of the old sessions 
(user,source,destination) ?

greet's

Claus

PS.: Could someone explain me why i have to set default_client_limit to 
5x default_process_limit?
