CI_DB_driver Bug?

Quoting the MySQL manual that was already linked in this thread:

By default, the server closes the connection after eight hours if nothing has happened.

Given that you're using a persistent connection, and you haven't got much traffic on the website ... it probably just times out when nobody visits your site for 8+ hours. Try setting pconnect to FALSE.

Right now i m on dev local system, which is windows 8.1 and wamp configured. but i keep constantly getting this warning, even several times in an hours, and sometimes i even get these on multiple consecutive page refreshes, after couple of hits it goes away. how can i suppress it, turning pconnect false increases my pages load-time.
