Database error messages

Hello,
I have a 2nd problem. Some times with the big number of users online, the sql server is down and i got thousands of database error messages, this is using 100 CPU, and so i have to remove the qmail queue, this takes some hours to have the server up again.
Please can i disable the database error messages ? and display another message, like an error have been occurred or something like that ?

You can change such settings here - in inc/classes/BxDolDb.php file:

define( 'DB_FULL_VISUAL_PROCESSING', true );
define( 'DB_FULL_DEBUG_MODE', false );
define( 'DB_DO_EMAIL_ERROR_REPORT', true );

Also I've made related fix some time ago, it makes debug output smaller:
