What dovecot version is this? with 2.3.17 or later you should probably use
service_count=0 here.
That would prevent auth-worker process from dying after each authentication and
then need for new process to be spawned for each authentication.
Yes, it is 2.3.17.
I give a try, it's slighty better. There is a little fewer stalled auth
processes.
But I didn't manage to go more than 2000 clients although in production
it's more than 8000 connections.
Maybe, it's because I didn't find how to make persistent connections
with imaptest and there was too many login/logout. I use delay to make
client during around 5 seconds
So I increase this delay up to 120s, this slow down login/logout and
decrease processes stuck in wait auth queue.
I think I will go this way to simulate normal load on this server.
But that doesn't simulate a reboot of service while clients are connected.
Thank you all,
