I'm running AGL demo on porter using ivi-shell, i.e.

cd /usr/AGL/CES2017
./switch_to_ivi-shell
./start_ALS2016_ivi-shell.sh

It starts well, but stops after several hours (definitely can't survive a night working). It is hard to say something more, because I couldn't get a debug log/crash reports from qmlscene. Any advice on how to debug it is welcome.

UPD: qmlscene doesn't crash, but the image freezes for some reason.

UPD2: Replacing qmlscene with qml in start_ALS2016_ivi-shell.sh I've got something in the log that looks like a cause of the freeze:

pvr_sync: PVR2DQueryBlitsComplete() failed. (ret=-8)

UPD3: Sometimes it just freezes silently

UPD4: It's no just a Porter problem, same on RPI3 On RPI3 it just crashes, which is probably another (and better manageable) problem.
