I have noticed the error below a few times in my logs(1st screenshot) and finally got around to looking into it today. The rule is shown in the 2nd screenshot.
On the settings page there are a bunch of scheduled jobs that do not seem to be getting cleared(3rd screenshot). This is a 5.0 rule, so maybe it's a bug I am not aware of or have forgotten about. Or maybe there is an issue with how I made the rule, if so someone enlighten me.
The last screenshot shows what jobs are scheduled after I clear the rule by clicking done and resaving. I think I had opened the rule before and looked at it and saved it again and I didn't see the error again for awhile. Apparently the jobs are queuing up and after so many it starts throwing errors.
