Constant Crashes - Why?

Hi,

The engine is constantly crashing for me. Sometimes I can use it for 20min, sometimes I’ll have 5 crashes in 5 minutes. I can’t find ANY common denominator. It can be when I click play, when I try open a blueprint, when I click compile inside a blueprint editor.

I’ve tried deleting all the DDC but that didn’t help.

The project has no custom code. Everything is built “in editor”.

ANY ideas?

Hello UnrealUser1337 -

We are seeing this crash call stack in the wild and are unable to directly reproduce it internally as of yet. Can you share your project that this is occurring in? If you would like to keep the project private, you can message a link via the Engine Forum’s Private Message System.

Thank You

Eric Ketchum

Thanks, yeah, I’d be willing to share privately. But… Where do I find the PM?

Something worth noting though, is that we’re several (three) people on this project and it only crashes on my PC.

You can use this link:

Hi UnrealUser1337,

I’ve been unable to reproduce this issue internally with your project. Can you attach your dxdiag info? I suspect this may be a compatibility issue.

-.

Completely missed this the last message. My apologies. Problem still remains and I’ve sent the DxDiag-log to Eric Ketchum on the PM-link above.

Thanks,

Hey UnrealUser1337,

After digging a little further with your MachineID, I found that you’ve been receiving two different callstacks. These are similar enough to each other to be identified as the same bug. The OTHER callstack that I found is already associated with a bug that is actively being worked on.

I’ve added THIS callstack and associated info to the active bug (UE-16510). Thank you for submitting this. Feel free to ask for an update anytime, but the current target release is 4.10 for this bug.
