Dual Connection and Database Connectivity Failure

[eluser]WanWizard[/eluser]
So sometimes you have this error, sometimes you don't?

You get this error when this call

Code:

// function db_connect(), in /system/database/drivers/mysql/mysql_driver.php
@mysql_connect($this->hostname, $this->username, $this->password, TRUE);

fails.

It could fail because one of the parameters is wrong (unlikely if it only happens sometimes), or because the server doesn't accept connections (for whatever reason). You could remove the @ in the command, to see the actual error MySQL throws you, or call

Code:

$this->DBr = $this->load->database(‘db_read’, TRUE);
echo $this->DBr->_error_message();
$this->DBw = $this->load->database(‘db_write’, TRUE);
echo $this->DBw->_error_message();
