Hi Midway! Are you on a VPS by any chance? If so, this is likely related to a cPanel error that was eventually patched out in future updates. If that's the case, the surest long term solution will be a cPanel update followed by a check to make sure that the CRON is back in place. 

Hi! I edited your message for your privacy, as it contained information that revealed your server details. 

On even well managed VPSs, the occasional cPanel process will fail and need to be restarted. Usually, notifications like these don't indicate a significant problem unless they happen all of the time. In this case, it looks like the cPanel process that causes things to restart needed to restart itself after an error. 

If you're just receiving an error message here and there, and everything is running smoothly, you're probably doing fine. Sometimes certain processes just need to restart after updates or other maintenance. If the same process is going offline multiple times a day, or a warning like this is followed by unusual server behavior, you'll need to work with your SysAdmin or contact our 24/7 Technical Support team to figure out the cause of the error. 

As indicated in the bottom portion of the message, you or your SysAdmin can adjust how often you receive these notifications based on their importance. Think of it like a warning light: sometimes it's for something serious, sometimes it just blinks off and on once and you're fine after. Hope that helps!
