Tvheadend

Hi, i'm facing frequent problems with TVheadend. Because of some reason the it stopps working and recording as well but the system service runs. So i can't get notice of it and just realize it if i want to watch tv. If i restart TV headend it works normally until the next freeze. Sometimes it works good for weeks but sometimes it hangs on daily.

System: Debian Stretch x64
TV Card: Digital Devices CineS7

My log is full of this. But i can't find any other entry which tells me what happens.
