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 the logging for such events? We want the tasks to run, but we don't want them to be logged.

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

Advice appreciated.
