SQL slow 5.6.0.2

Permalink
I get this error message (see code block below) when I navigate to my sites version 5.6.0.2

When I refresh the page the site comes up. I would like to update to newest version (5.6.1) but update is not available from Dashboard.

I like the new features, but even with all caching options on my sites running 5.6.0.2 seem sluggish.

Error occurs on Acorn Host who use a 20 second timeout to protect against DoS attacks
Their response...
"Our server has a wait_timeout of 20 seconds. If your script can just retry its query if the timeout had occurred. Do you know if the code can do that?"
Error message does not occur on HostGator but sites are slow to display.

Error message...
