It's very easy for brute-force attacks from botnets to consume all your SSH process slots and then you are locked out.

Can confirm, had this problem the other day. CI started failing and after a short investigation I figured out sshd was just dropping my connections. Installed fail2ban first, but then just used a firewall since all valid IPs are known.
