New matomo w/ bitnami ova installation issue

Hi all,
I’m new here and have loaded up a bitnami (debian) image of matomo with vmware 2vcpu 8GB RAM.

The site is up and running, tracking and recording sites as intended however, the matomo site crashes and is unreachable randomly. Sometimes waiting 20-60 minutes and the site will be back up but most of the time, I need to reboot the server for it return. During this time, the apache and db services are still up and running. sometimes restarting apache fixes it but usually not.
