MySQL gone away issue

[Zifius]

Hello Fabrizio,

I have recently moved to another hosting provider and now from time to time getting this report:

a:4:{i:0;s:63:"SQLSTATE[HY000]: General error: 2006 MySQL server has gone away";i:1;s:1306:"#0 /var/www/vhosts/site/store/lib/Zend/Db/Adapter/Pdo/Abstract.php(305): PDO->beginTransaction()

#10 {main}";s:11:"script_name";s:42:"/var/www/vhosts/site/store/index.php";s:4:"skin";s:5:"admin";}

Can you advise what might be wrong with it and a setting to look into?

Thank you
