Thank you for the response. It's been awhile, but I'm finally getting back to this issue.
Our max_allowed_packet is set to 512M.
Our max_execution_time is set to 600.
We're getting the same error when attempting to duplicate the quiz as we do when attempting to take the quiz.
It seems we don't have the option to do a health check. Is there another way to check the quiz to see if there are any underlying problems?
