Nextcloud 15.02 Postgresql

Hi all,

I am currently running Nextcloud in a VM on version 15.02. I have noticed that once a day my Nextcloud instance becomes unreachable and when I do a systemctl --failed I see that the process "postgresql@10-main.service is loaded but not running. When I restart the service the instance works again just fine. This seems to happen once ever 24 hours and I am not sure why. Any thoughts are appreciated.
