A background job of type 'Persist Core state', summary 'Persisting Core state', has failed.

I have a Rapid Recovery Core that started showing this error a couple of times a day. 

Date/Time: 07/18/2022 16:15:05 -04:00

 

A background job of type 'Persist Core state', summary 'Persisting Core state', has failed.

 

Storage Connection Exception

 

Assume the mongo database is still unavailable.

About this event: A background job has failed.

Backups seem to be completing normally. I have confirmed the Mongo service is running. I have also run a repair on the application and error continues. Searched the knowledgebase but cant find anything pertaining to this. Any ideas?
