this is a normal message emitted by the driver each time a new database connection is established against the database; oslo.db sets up the SQL server mode on new connections (I need to review the code to re-examine the specific methodology). as far as if it is suddenly emitting to the logs where it was not before, has this just started occurring where it did not previously, and if so what changed? leaning towards no bug here but will examine to see if the messaging is inappropriate or unexpected.
per the customer they had DEBUG logging set up in nova.conf that would be causing this.
