to developers, ue 4.14 crashes! - Error: 0x887A0006 - 'HUNG'

Still Experiencing Driver failures in 4.14.2

The issue on my end can be triggered from editing mesh and material slots to moving the mouse over various actors and objects details to opening and closing Blueprints, most things can trigger a black screen and then crash to desktop with a Driver recover bubble popping up.

Things i have tried,

New drivers, checked Card temps , memory checks, clean projects in 4.14.2, etc

My card is on the low end Nvidia Geforce 610 GT but it worked well enough for me in 4.13 and prevoius engine builds with little to no issues other then low FPS when i had a ton of higher end render effects or lots of geometry going on.

I love the features of 4.14 and really want to make use of this and future versions but things are to much like a mine field at the moment to use this engine thanks for working on this issue and this engine.

This is almost certainly graphics card driver related bud. I have been having this issue with UE4 for months now on and off, from around version 4.11 to 4.14, I tried almost literally everything and the only solution I found was to downgrade my video card drivers.
I also gave my system a clean as it was pretty dusty.

I’m using an AMD card though so the drivers I am using are 15.12. Since installing them I have had zero issues in over a month now, whereas it was crashing 4 or 5 times a day before that with the latest 16.12 drivers, and every other driver version since 15.12.
So check around to see which older Nvidia drivers are confirmed stable and get them installed.

Good luck!

4.14.3
This is still a thing, crash crash and more crash.

Crashes repeatedly for me. I’m losing my marbles. 4.13 worked fine, 4.14 makes an nvidia quadro 1000m with 2gb ram die. I will post specs or crash reports if they’re pertinent but I am super bummed out right now.

Adding my experience to the pool of unlucky users.

Crashes as well on a R9 380. Drivers have been updated.
4.10 engine was not crashing
4.14 crashes randomly
No other games crashes.

And it looks like Epic already fixed it. Unreal Engine Issues and Bug Tracker (UE-37999)
Though, won’t be released until 4.15, not hotfix for 4.14 ?? :eek: :eek: :eek:

We have fixed one cause of the crash, but other causes still exist and are under investigation. The fix actually went into the 4.14.2 Hotfix, and our data is showing that we have reduced the frequency of the crashes (or rather the number of users who are experiencing them) by possibly up to about 40%. We will continue to work to identify the cause of the remaining crashes. Sharing your system specs and 100% repro steps (including assets that cause the crash) can help immensely. (please post your information to the UE4 Answerhub Bug Report section.)

Thanks

Hey Stephen,

I’ve posted my report here : Graphic driver Crash - AMD R9 380 - UE4 AnswerHub

It wasn’t easy to get though, most of the time the Editor would crash without generating a report.

Thanks

I think I might have found a workaround solution for now!!! In the content browser pane: click the little eye that says “View Options” and uncheck "Real-Time Thumbnails."

I spent several minutes rapidly rolling my mouse over mesh/materials preview windows, while in a blueprint, and it hasn’t crashed yet! Normally, it would have crashed in <5 seconds of doing that. Nothing has changed, in terms of my laptop. Before unchecking that option, even while in 4.14.3, it would still crash every time.

Wow! After uncheck "Real-Time Thunbnails, editor is working well.
Thanks IronicParadox.

Nice find IronicParadox turning off Real-Time Thumbnails has reduced the crashes i was having in 4.14.3 by a significant amount, i still get a crash when opening an instanced material shortly after compiling a parent but if i wait for the compile to complete it dose not crash.

Before finding the above workaround i had been testing the launch option -opengl4 which in my case stabilized 4.14.3 for what i use it for i did notice some material setups i had made did not function in this rendering mode.

Glad it helps! Yeah, I had been stuck using opengl as well and it’s compatibility/performance isn’t all that great. I spent a great deal of time trying to rule things out and it all honed in on the real-time thumbnails. I can’t even tell you how many hours I spent trying to figure it all out.

The only other thing that I’ve noticed is that it does cause a little bit of hard drive thrash on each thumbnail highlight. I’m probably going out on a limb here, because I don’t really know the inner workings of the editor or the graphics drivers, but maybe the graphics card expects information to be loaded and if the hard drive doesn’t load it in a specific amount of time, then it causes the graphics card to hang or be removed(my error is almost always gfx removed). Another possibility is that it’s getting stuck in some infinite loop; which sounds the most likely to me. I’m sure a dev could debunk these theories though.

I can definitely say that as the program gets ready to crash, gpu usage shoots up to 100%. You can even draw back the settings to the point that the card doesn’t even use 30% of the gpu, while playing in viewport, and it will still shoot up to 100% usage when the thumbnail crash happens. I will have to play around with it all some more and see because it doesn’t seem to be tied to the TDR settings either. I can set TDR to something higher and all it will do is make my computer sit there for that duration before it crashes the rest of the way out. You can try underclocking into oblivion and it doesn’t change anything either. Example: I can underclock to 1/5th of the gpu’s normal stats and it will crash every time.

I’m on 4.14.3 binary version. Currently, as soon as I open my master** animation blueprint** this crash occurs. My animation blueprint is quite complex and uses many nodes and I had ~6 tabs open. This crash didn’t occur in 4.12.5.

Is the new layout of the animation editor more rendering intensive?

Thank you IronicParadox, 4.14.3 was unusable until i turned off “real-time thumbnails”. Whether it still crashes from other issues . . . i hope not. But again thank you, had been very frustrating.

I switched to Forward Rendering and have since then no more crashes. I think the GBuffer got too big to handle for my graphic card when using the animation blueprint.

Hi all.

I’m glad that some of you are finding workarounds for this issue.

I want to update all of you that we are still looking into these crashes, and we have logged a new ticket for tracking them: Unreal Engine Issues and Bug Tracker (UE-42280)

Cheers

Turning off the Real-time Thumbnails seems to have helped here. I also disabled realtime view in the editor, show FPS and stats and the r.[something something] setting.

I just updated to 4.15.2 (from 4.15.1) and am now having this problem for the first time ever. I crash randomly within 5 minutes of running the game. I have a gtx1080 and have the latest drivers installed. Very frustrating that I can’t go back to 4.15.1 which worked great for me. (My performance is always significantly worse with sceneCaptures.)

I have the same problem.

same problem on NVidia drivers (382.05). Older drivers were not showing the crash. You can try reverting to a previous driver.

My UE 4.16.1 suddenly became very unstable and is constantly crashing with this issue :

Crash due to D3D device being lost. (Error: 0x887A0006 - ‘HUNG’)
https://issues.unrealengine.com/issue/UE-42280

So after reading about this i’ve tried the following solutions:
-Remove 4.16 completely and reinstall. : FAIL
-Uncheck realtime thumbnails in content browser : FAIL
-Downgrade the nvidia display driver to legacy versions : FAIL
-Use MSI Afterburner to clock down the GPU : FAIL
-Run Engine with -dx12 : FAIL
-Change to use forward render : SUCCESS

So all attempts to fix this fails except removing the deferred render option.
But this is no solution, as i need the deferred render for my project.

So is this a pure driver issue? 4.14.3 works without any problems.
Is there a fix in sight? as per now 4.16 is broken for me :frowning:
