Cause

MaxStartups was not set within the sshd_config files on Vertica cluster members

Resolution

Edit /etc/ssh/sshd_config and enable MaxStartups as per the Vertica documentation:

https://docs.vertica.com/12.0.x/en/admin/backup-and-restore/setting-up-backup-locations/configuring-backup-hosts-and-connections/

As an example, one could use: 

MaxStartups 100:30:100

Once this is set and saved, you will need to reload sshd:

systemctl reload sshd
