I am not able to connect to my database due to an error in class/database/databasefactory.php line 34 Below is the piece of the code that is causing the error. This is strange an may be a server issue instead of an XOOPS issue. Any ideas?

function &getDatabaseConnection()
{
static $instance;
if (!isset($instance)) {
$file = XOOPS_ROOT_PATH.'/class/database/'.XOOPS_DB_TYPE.'database.php';
require_once $file;
if (!defined('XOOPS_DB_PROXY')) {
$class = 'Xoops'.ucfirst(XOOPS_DB_TYPE).'DatabaseSafe';
} else {
$class = 'Xoops'.ucfirst(XOOPS_DB_TYPE).'DatabaseProxy';
}
$instance =& new $class();
$instance->setLogger(XoopsLogger::instance());
$instance->setPrefix(XOOPS_DB_PREFIX);
if (!$instance->connect()) {
trigger_error("Unable to connect to database", E_USER_ERROR);
}
}
return $instance;
}

That's a generic error you get when there's something wrong with the database or connection. Was your site working before the error? If so, the MySQL server could be down.

Might like to check out this FAQ

My site gets this alot....esp when its under load, mainly when the image gallery is being hit hard. Seems MySQL doesnt respond... or there is a limit on the connection attempts per user to MySQL for my user. Enabling caching fixed this anoyyance. Wish we could have a "SQL Server Busy Try Again Later" error.
