Come accross my daily reading site -BERNAMA (Malaysian National News Agency) that they do not secure their page well.
I always educate the market about do not expose their error message to the users and we suppose to show a general error messages while we always can log the error message in private file.
Look at the message it can even tell user which line of code got the error message. Look at the erroe message it seems like there are too many incoming connection to MySQL and need to flush all the hosts to release the connection.
If anyone know a friend who work in BERNAMA, please ask them to fix it ASAP. Bad Habit!!!
