Libreelec 8.0.2 freezes

I'm running libreelec on Wetek Play 2 from nand and after a few hours of running live tv (dvb-s tuner, tvheadend) whole libreelec freezes for few hours (12 and more) then it starts working again. Unfortunately I can't get a debug log because it takes a long time to get to this error and debug log wouldnt fit into my box's storage.

I attached system, kodi and tvheadend log.

dmesg.log kodi.log tvheadend.log

I am using HTS Tvheadend 4.2.2-32 ~ LibreELEC Tvh-addon v8.1.111 . I also tried 4.0 but result was the same.

I don't have any other machine which this device could be connected to, but I don't think that this is a hardware failure. At first I tried to use We OS (android based system from Wetek) and these kind of freezes hadn't been happenning (I had another problems with it. stuttering etc...).

I have done some further testing and discovered that when I leave it on certain channel for whole time. System every time freezes after same amount of time (about 7 hours and 26 minutes). I've tried it 3 times and always the same result.

I let top run for whole time until ssh was disconnected. Screenshot of last response of top command.

I have no add-on except oscam, tvheadend and tvheadend pvr client. All those are needed for live TV.

After about 7 hours and 20 minutes I switched the log level to DEBUG. It seems that tvheadend htsp client addon has some kind of problem.

kodi.log

At this point tv no longer responds and even if I try to change a channel TV is still frozen on same image. I can quit PVR and relaunch it on different channel and it is still frozen on the same image.

When I tried to connect to tvheadend through VLC it worked normally. TV in kodi started to work only after I manually disconnected pvr addon from tvheadend.
