How to disable Scheduler logging in CF10

Hi,

In the coldfusion-out.log we are seeing scheduler log entries like this:

Nov 11, 2014 20:54:14 PM Information [ajp-bio-8012-exec-127] - Starting HTTP request {URL='http://somesite.com:80/1.2?output=xml', method='get'}

Nov 11, 2014 20:54:14 PM Information [ajp-bio-8012-exec-127] - HTTP request completed  {Status Code=200 ,Time taken=313 ms}

Nov 11, 2014 20:55:00 PM Information [scheduler-2] - Run Client Storage Purge

Nov 11, 2014 21:00:00 PM Information [DefaultQuartzScheduler_Worker-1] - Task default.blah triggered.

Nov 11, 2014 21:45:00 PM Information [DefaultQuartzScheduler_Worker-2] - HTTP request completed  {Status Code=200 ,Time taken=773 ms}

Quite simply, how can we disable them?

We have no logging enabled for scheduling in CF10 Admin, and yet they are still generated.

Advice appreciated.
