I have got this email. This is awkward because we never have used pager. I have checked this monitor, and pager is not configured in alert section. Also, I have seen in This System Alert's delivery can be configured in Settings -> System Alerts, but there is not Pager alert in it.
FAILED TO NOTIFY VIA PAGER (Error=Failed to send message). Original message:
