I renamed qmail-remote to qmail-remote.now and then restarted qmail service. No qmail-remote PID appear.
Now, i config "spam status" in a demo domain and nothing change, i need retart qmail to apply it.
I think the Master use qmail-remote PID to control Mail Slave, but some bug lead to RAM increases
My cluster:
10.0.0.240 Master,
10.0.0.241 Web server (Apache) + Mail server (Qmail),
10.0.0.242 Mysql server.
Now i use the "Cron Scheduled Tasks" to restart qmail service once a hour.
