At my parents while hard rain and lightning the signal is sometimes lost completely (90 cm dish directed and adjusted to ASTRA). Just a few minutes ago two of three kdvb-fes on a server I'm maintaining suddenly jumped up to 40 % each for some seconds. Usually they're between 0.1 - 1%. > > I also do not understand for what all this additional CPU-load is used. > > the driver is trying to (re-?)aquiring the signal by zig-zag-scanning > the frequency range around the center frequency.

Think about four cards in a machine starting zig-zag scanning because of some lightnings and the machine acts like slow motion. Some limit in the driver like all kdvb-processes together mustn't have more than 20% CPU-load would be fine.
