3.5 Upgrade Causing Database Problems included PHP error_log

I have noticed my site loading speed has been bouncing all over the place since my upgrade to 3.5. When I would first log in to the Dashboard, the site would all but crash. I got rid of some troublesome plugins but am still getting the database error in my PHP error_log below.

Can anyone point me in the correct direction to address this issue? It would be greatly appreciated.
