Hello everyone, I'm representing a performance problem on my server.
I explain in detail the configuration of my server.
I am using postfix with 46 IPs configured as a mta, with round-robin, in
the master.cf file
I think the "cleanup" process is responsible for the excessive use of cpu.
ps fax | grep -c cleanup
181
Is there any way to limit it?
I have modified the maxproc in the master.cf file but the change was not
made.
