Ohai,
we’ve just completed the migration of Redmine (aka projects.theforeman.org) to a new home.
While doing so, we also upgraded it to the latest Redmine release (5.0.5).
This should fix any stability issues we had with it in the recent months.
You can read the details of the migration in Update Redmine and move to new infrastructure · Issue #1681 · theforeman/foreman-infra · GitHub
