I was receiving a warning that one of my backups was suddenly failing. I received an email stating that I should check: /usr/local/cpanel/logs/error_log In this log, I found: info [cpanellogd] Invalid domain in /var/cpanel/users/usernameexample XDNS entry, skipping In /var/cpanel/users/usernameexample I found 3 entries at the bottom that don't look quite right. There was a typo in one of them and I cleaned it up. I'm not sure that they should be there though. Where do these come from and where are they set? And, why are my backups just suddenly failing, or at least I'm just suddenly getting a notification that it failed?
