I am using dnn 8.00.04 and I have multiple nightly application starts always preceded by the event web server updated. This occurs every day starting around 9:17. The schedule system then seems to run all daily scheduled tasks right after start which then throws them off from their normal schedule
I only have on server and there are no messages in windows logs that may be related. My application pool is set to restart itself every 29 hours and I can see this is not related
