Since I upgraded to Civi 5.11 (from 4.7) I am seeing empty emails from the cron daemon every time it runs the scheduled jobs. Previously I have only had emails when there has been some issue with the cron or what looks like an error from one of the scheduled jobs. The scheduled jobs look to all be fine in the log.
The problem is that it would hide any genuine error messages as I'm not going to go through all these emails.
