Apache WebServer Disable's Before any Updates are installed

Hi i am having the since October 2018 till now . When ever there is an update to virtualmin my apache turns off and then i get of Error 511 on the website. i have to login to virtualmin and start the apache server. Does any body have a solution for this or link to related issue.
i am running Virtualmin version 6.05 on Digital ocean, I can access virtualmin when the issue causes but my domain does down, like every week.

Hi i have just checked my webmin > system > scheduled cron jobs
And this were the results
