A lot of Flapping hosts every 60 seconds

Im using Ping yeah…
The Icon appears but looking at the graphs that services provide, they’re still getting data, so I don’t understand why it shows as stale even tho we’re getting the data.
The pings looks state but if I reschedule an active check it goes up again.
Also sometimes it says that the host is in stale but the last check was 220seconds ago…
