New Mysql_error Warning

Installed 7.0.3 a week ago.  Just started getting this:

                <div style="border:2px solid red;padding:4px;width:600px;margin:0px auto;">
                    <div style="text-align:center;background-color:red;color:white;font-weight:bold;">Error</div>
                    <div style="text-align:center;">Database connect failed</div>
                            </div>
           
Warning: mysql_error(): supplied argument is not a valid MySQL-Link resource in /home/.../inc/classes/BxDolDb.php on line 453

Fatal error: Call to a member function getParam() on a non-object in /home/.../inc/db.inc.php on line 83

Line 453 is:

            $sMailBody .= "Mysql error: " . mysql_error($this->link) . "<br /><br /> ";

Line 83 is:

   return $GLOBALS['MySQL']->getParam($param_name, $use_cache);

Anyone know what this problem is and how to fix it?  Thanks.

This is MySQL server problem. This error can occur if MySQL server is down or during MySQL server restart. Please contact your hosting provider if MySQL server is functioning properly and if they restarted it recently.

Hello,

I have the same problem. I tried 4 times in different moment of the night, and the upgrade give me the same problem.

I can't go to 7.0.3

I've tried to change mysql_pconnect with mysql_connect (my provider doesn't support mysql_pconnect) and now I have this message:

I also made this change to my database:

UPDATE `[databasename]`.`sys_options` SET `VALUE` = '7.0.2' WHERE `sys_options`.`Name` =  'sys_tmp_version';

I think because something gone wrong during my last update from 7.0.1 to 7.0.2

Now works fine!
