I got same situation or error message and the issue in my particular case was that the number of connections was set to a maximum of 500. similar issue happened when this limit is reached therefore you can either reboot the SQL instance to get rid of idle connections. But if this happens frequently change the number of connections to unlimited (Value 0).
