Mysql Queries That Vanish?

[eluser]Eric Brown[/eluser]
We recently witnessed a strange issue. Without notice or changes to models, many of our queries are no longer making it to our database from the CI app. We noticed that at exactly 2am UTC on the 19th only 15% of the queries sent to our table make it. They don't show up in the mysql bin log and yet we aren't getting any connection errors, anything in the CI logs or the web server logs. Any ideas on troubleshooting?

Add this to your main controller MY_Controller if your using it in the Constructor.

Code:

$sections = array(
     'config'  => TRUE,
     'queries' => TRUE
     );

$this->output->set_profiler_sections($sections);
