CRE LOADED- 2006 - MySQL server has gone away

When trying to update the catalog on our CRE 6.2 PRO website, I am getting the following error: 2006 - MySQL server has gone away select products_parent_id from products where products_id =6570 [TEP STOP] 2006 - MySQL server has gone away select count(*) as total from sessions where sesskey = 'ae669dc5ab550949d5d8d02536ec8fac' [TEP STOP] According to the Hosting provider, our CPU usage is exceeding the limit, which is causing the problem. They suggest that we optimize the site so that it does not hit this limit. Please only bid if you have resolved this problem before.
