In Global.php it is like this:

// ################################################## ###########################
// start server too busy
$servertoobusy = false;

if (strtoupper(substr(PHP_OS, 0, 3)) != 'WIN' AND $vbulletin->options['loadlimit'] > 0)
{
if(!is_array($vbulletin->loadcache) OR $vbulletin->loadcache['lastcheck'] < (TIMENOW - 300))
{
update_loadavg();
}


if ($vbulletin->loadcache['loadavg'] > $vbulletin->options['loadlimit'])
{
$servertoobusy = true;
}
}

I have tried to change $servertoobusy = false and also the last $servertoobusy from true to false but still the same error.
