Spawning new servers on app startup

On Application startup I have:

app.UseHangfireServer();

But this seems to spawn new servers on App startup…is this expected behaviour…or should I only have one server? How do I prevent this?

Look at the heartbeat time in dashboard, previous server is dead and there is no heartbeat but it still lingers around for a bit in case it comes back. Hangfire doesn’t know it’s from the same app.
