Oh, the dovecot master process is eating the CPU. That's interesting.
This is the first time I've heard it doing that. What does it show when
you do strace -p -tt to it for a second or so?

I don't think you should have that many of login processes.
login_process_count should be about the same number as you have
CPUs/cores. Rather increase the login_max_connections if you need to.
