Hi,
Interesting case. I looked up this message in the syslog translator, and it says:
Message Name: app.log.emerg
Severity: EMERGENCY
Corrective Action: Contact NetApp technical support.
Description: This message occurs when an application encounters a fatal error and requires immediate attention.
Error reported in your snapcenter/filer side:
app.log.emerg:
tnadb1: SnapCenter VMware OVA Software 4.2: (0) Info: Backup job [32],
Host Name [ltnadb1], Host OS [Linux], Resource Group [Daily Backup of VMs], Resource Group Size [68], Policy [SMVI_DAILY__2], status [completed successfully], Completion Time [00:01:44]
Looks like the client application that generated this event, is SnapCenter VMware OVA Software 4.2, Host Name [ltnadb1]
Next suggestive action: Even though the backup jobs are not failing, but still it is worth investigating the reason behind 'fatal' eror being flagged. It is certain that it is being flagged from the application i.e tnadb1: SnapCenter VMware OVA Software 4.2.
Could you share the logs with us :
Snapcenter host agent logs
plug-in logs
This will help us determine if it's wrongly reported Or is it a genuine error.

On the side note : It is worth raising a ticket with NetApp. {As far as interoperability is concerned, looks like a supproted configuration}
