TVheadend rescans all the time, tv not working

  • Hello,

    every couple of days the TVheadend scans in the right upper corner loops every few seconds and the TV Button does not come up.
    Sometimes it helps to rescan the channels in the backend.
    Today the box did crash while switching a TV Channel, after that the problem start this time.

    Any chance to debug this?

    Im running milhouse generic.
