Tvheadend

I have been using an internal XMLTV grabber called epg.gravi.hu. Today I observed that Tvheaend is continously restarting after 1-2 minutes of watching TV. I concluded that the restart occurs when internal XMLTV grabber is triggered. The workaround was that I disabled the grabber. Now tvheadend works fine.

Tvheadend is running on a wetek play, with Libreelec 7.0.2. The addon version is 7.0.444 -> Tvheadend 4.1-2267, the same fault is present with 4.1-2278

The only log available is service.log these were the last line before the restart (crash):

2016-10-16 19:52:35.000 [ INFO] xmltv: /storage/.kodi/addons/service.tvheadend42/bin/tv_grab_gravi.sh: grab /storage/.kodi/addons/service.tvheadend42/bin/tv_grab_gravi.sh
2016-10-16 19:52:35.029 [ INFO] spawn: Executing "/storage/.kodi/addons/service.tvheadend42/bin/tv_grab_gravi.sh"
2016-10-16 19:52:35.958 [ INFO] xmltv: /storage/.kodi/addons/service.tvheadend42/bin/tv_grab_gravi.sh: grab took 1 seconds

I attached the XML file which is provided by the grabber. I had a quick look into it but saw nothing suspicious. Probabyl the XML file is corrupt however Tvheadend should not crash due to corrupt input.
