I updated to version tvheadend_4.1-363~gf632da3 with no effect.
But know I found error messages in the syslog, so that it is clear, that the error is on the server-side:

The Tvheadend-process was terminated so that I have to start it manually again.
Can someone find out, what happened? And how to fix?
