Environment

Release : 12.0

Component : ESP REPORT SERVER

Resolution

It should be related to the restart of DB was performed while report server is running. Most probably the first message was generated because of broken connection to DB. And most probably the second one was generated while the report server attempted to connect the DB again and DB refused the connection.
