Error: Unable to find service node for ip address with id=6

[JP Kelly]

When trying to access the settings for mail on a domain I get the following error:

Error: Unable to find service node for ip address with id=6

I understand this is a problem with the database but I am not sure where to look to fix it.
I only have 4 IP addresses on the system.
