Built in Functions stay up

Hello
When I use Probes with the built in functions (cpu, disk,…) the probe never goes down even if the server is powered off. We tested it this weekend. All other Probes went down, but the ones with the built in functions never went down. So the entire server stayed in status partitialy down instead of down.
Any idea why???
Thanks Reto

I can confirm this behavior (Dude 2 beta’s from some point, 2.0, 2.1 and 2.2).
