Blue screen of death on light building

November1986 · March 19, 2014, 8:19pm

I have a AMD FX 8350 , 12GB RAM , 2GB PNY 670 Video Card, Windows 7 64 bit, and recently when I tried to rebuild lighting on a project with unreal engine 4, my first attempt to rebuild lighting since I got the engine, I got a blue screen of death. Has anyone else had this issue? Or is my computer in massive need of more memory before I try this again? It was already in the plans anyway, but I’m wondering if I should hold off until I can get the ram.

Ok oops…didn’t mean to answer my own question. Anyway, unfortunately I was unable to get much information with the quick BSOD but it was a memory dump. Although I may have jumped the gun as it hasn’t happened again. On the other hand I’m getting No importance volume found when trying to build now and I think I’m just getting way to far ahead of my self trying to build a landmass, when I am literally just starting out learning to use the program all together.

Hi November1986,

Are you getting a Memory Dump blue screen? Does this only happen when you are building lighting? Does it provide you any text and if so would you mind sharing this so we can better assist you?

Thank you!

Has this happened more than once? Every time you build?

Well I may have jumped the gun as it’s not going BOSD anymore but now I get No importance volume found. I think I’m just getting ahead of my self here as I’m literally just learning as in…the last hour.

Gotcha! Ah, yes. The Importance Volume. Getting started – try here:

Just in case you don’t know that tool or someone else has problems:

Use memtest to check your Ram: Memtest86+ - Advanced Memory Diagnostic Tool (Download iso, burn it and than boot from it).

Thanks for showing me those videos, been watching them for a while now. Although I tried to start a new project and during a simple attempt to make a house like seen in some of the videos I had another BSOD, this time it said system service exception and as usual did a memory dump. When it happened I was trying to “launch” what I was doing instead of clicking play, kind of curiosity I guess. It got to cooking and…well…yeah.

AMD Radeon HD 7800M - Getting BSOD at random times. Error is:
REFERENCE_BY_POINTER. I have the latest Catalyst drivers.

Attached is my dump file shot

This is only happening in the UE4 editor at random times. I’ll try and note when it is happening

I had this twice when building lights too. I see the Swarm agent firing up, and my PC blue screens instantly. Win 8.1, Nvidia GeForce GT 750M x2 with latest stable drivers.

It is the 4th time I get a BSOD when building lights, out of maybe 10 attempts. I’m on Win 8.1, Nvidia GeForce GT 750M with latest stable drivers.
It occurs less than a second after clicking the button, as soon as I see the Swarm agent icon in the system tray. The actual error given is PAGE_FAULT_IN_NONPAGED_AREA.

Are there settings I can change on the building process to make it safer ? Maybe disable hardware acceleration or something along these lines ?

FYI, I was able to get rid of this by setting the number of processes to 1 in SwarmAgent.

if you’re still having trouble.

go to C:\Program Files\Epic Games\4.9\Engine\Binaries\DotNET and open swarm agent.
then open up task manager and right click swarmagent.exe then set only 1 or 2 of your cpu processes to use then build your scene.
you can also lower the priory so your over all pc doesn’t take as much load

Just got BSODs today on my 10900K and 3080. Would BSOD as soon as lighting starting building after the export data.

I turned on the Developer Menu under Setting, then dropped:

LocalJobsDefaultProcessorCount from 18 to 8
RemoteJobsDefaultProcessorCount from 20 to 10

That seems to have fixed it.

Any ideas why letting Swarm use 18 and 20 (since I have 20 threads) causes this to BSOD?
