Qgroundcontrol freezes under win8.1

[hicham1492]

Hi;

The Qgroundcontrol keeps freezing (not responding) after a few munites of use. Below are the details of the OS version, Qgroundcontrol version, autopilot board and autopilot firmware, then the steps to reproduce the issue.

• Ground station operating system: Windows Embeded 8.1 Industry Pro running on ZEBRA ET55 tablet

• QGroundControl version and build: version 3.2.7 latest downloaded on 09Jan2018

• Autopilot board: Pixhawk 1

• Autopilot firmware: Installed 'ArduPilot Flight stuck' ArduSub V3.5.2

• Exact steps to reproduce the problem. 1- Start Qgroundcontrol 2- Plug in power to the ROV 3- All connected correctly, we then receive video stream from the ROV onto Qgroundcontrol. 4- We run some few tests, like running the thrusters, moving the camera and confirming the video stream is correct, moving the map, all happy. 5- After a while, could be few munites, the qgroundcontrol freezes. The video stream with the map freeze and message says "application not responding.

When watching the qgroundcontrol process on the task manager, the memory allocated to qgroundcontrol keeps growing, when it reaches 1.4MB a popup comes up saying "(QGroundControl.exe:3828): GLib-ERROR **:gmem.c103: failed to allocate 96091 bytes"

I have taken a process file dump, I am not sure where to upload it as it is around 970MB. I have switched on and saved console log for all the modules. The last logging at the time of the freeze is shown below.

Any help in finding the reason behind this issue will be appreciated. Is the issue is due to the operating system I am running on? Or, the tablet I am using? Or something else?

Many thanks Hicham

Can you put the dump file on dropbox or google drive and put a sharing link here?

[hicham1492]

Thanks; I have upload it in google drive, see link below.

These are the links again with the log file too and some snapshots of the task manager.

Just would like to add more details of the tablet we are having the issue with:

Intel Atom CPU Z3795 1.6Ghz Display adapter: Intel HD Graphics Display driver : igdumdim64, igd10iumd64, ...,igdumdim32, igd10iumd32. Memory 4GB Win 8.1 Embeded Industry Pro 64bit x64bit processor

By all means I am ready to test any code fix that you could provide on the device I am using.

an question on the side: "What would be the best computer/tablet specification that the QGC works perferct?"

[jaxxzer]

Not much useful in the call stack. I've no idea what to make of this.

@DonLakeFlyer is it possible to switch to Qt 5.9.4 or 5.10.0 for Stable 3.3? Then we will have debug symbols for the Qt libraries.

https://bugreports.qt.io/browse/QTBUG-3934 https://www.appveyor.com/docs/build-environment/#qt

[DonLakeFlyer]

3.3 is pretty much done. Switching to a new Qt is a royal PITA.

[DonLakeFlyer]

GLib-ERROR **:gmem.c103: failed to allocate 96091 bytes"

This would seem to indicator gstreamer doesn't it. Not sure any other code in QGC uses GLib? Anyway is the memory leaking not reproducible? I would tackle that first. Try turning off video and see if the leak goes away.

[hicham1492]

I have run few tests with the video stream off, and the issue still happened. The memory leak in this case is hapening slowly (by me watching the task manager) compared to when the video stream was on. I have uploaded a new dump file while the video stream was off

https://drive.google.com/open?id=1xg6qh_widWJ7IrJDSAjqcK4oYfovAW9e

[hicham1492]

Actually, the memory did increase to 348MB but QGC didn't crash and no message showed up with the Glib-ERROR as before.

[hicham1492]

Just to clarify, when I said QGC didn't crash, I meant it stopped responding but did not crah with the memory leak.

[lida2003]

QGC is very slow to launch, and switch to setting tabs. Any one knows why?
