States that there is 1 connection beyond your maximum number of connections for users with the super privilege.
My question is can you increase that number? Eventually I want to put limits in for all users that leave additional connections open for administrative jobs, but I'm not in a position to do that right now.
I want to increase that number to 10 so I can have replication jobs and monitoring jobs not affected by application connections.
