For amavis:

Edit /opt/zimbra/conf/amavisd.conf and reduce the max_servers (it's at 10 now) down. 5 is a good place to start.

For logger:

Either edit /opt/zimbra/conf/my.logger.conf and reduce max_connections, then zmloggerctl stop, zmloggerctl start
OR
zmprov ms -zimbraServicesEnabled logger
zmloggerctl stop
to stop it completely. You'll get an error when you log into the admin console after this, and get no status or statistics in the admin console, but those aren't fatal.

You could also reduce max_connections in /opt/zimbra/conf/my.cnf and zmmailboxctl stop; zmmailboxctl start but that's not recommended.

If your spelling is good, you can shut down the spell server, and remove it from zimbraServicesEnabled much as the logger is above. Or, change /opt/zimbra/conf/httpd.conf:

StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 50


Lower the first 3 (NOT the last 2) to cut down the number of apache processes running.
