Some services that are not started anymore

Hi,
GitLab-ce 13.6.2
2 weeks ago, I noticed that some services are not restarting anymore :

gitlab-ctl service-list
alertmanager
gitaly*
gitlab-exporter
gitlab-monitor
gitlab-workhorse*
grafana
logrotate*
node-exporter
postgres-exporter
postgresql*
prometheus
puma*
redis*
redis-exporter
sidekiq*
unicorn

missing crond and registry !

Moreover, the number of processes has increased from 786 to 2400 since Nov 24th (seen in Sidekiq). !

It looks like GitLab-ce is working just fine…

Should I be worried?

Thanks
