Hi, sometimes, but I don’t know when exactly, UnrealFrontend gets frozen. The UnrealFrontend process is still running, the UnrealAutomationTool is still running too, but the UnrealFrontend window is frozen.
Hello,
I have a few questions that can help us reproduce the issue on our end:
- What exactly are you doing when the freezes occur?
- Does this occur regardless of the project you’re working in?
- Are you able to provide steps we can follow to reproduce the freezes on our end?
- Are you getting any increase in memory usage while this freeze occurs?
Hello ,
When this freeze occurs, I’m making a packaged version of my game (compiling, cooking and packaging), and obviously when I’m building/cooking, I’m using 100% CPU, and a lot of RAM.
Sometimes it happens on the editor too when I cook the game.
Thank you for the additional information.
Could you please provide your dxdiag?
How often is this freeze occurring? Does it happen every time you attempt to package your game?
Yes, this is the dxdiag:

Anyway I don’t knwo how often is this happening. Maybe when there are long build times.
Seems like in the packaged game, sometimes, expecially when using a lot of memory (for example when loading maps), the game stops working. Maybe it’s related to this issue.
After looking over your dxdiag, I’m thinking that the amount of memory that your PC has is causing UFE to freeze. When you are experiencing the freeze, does the cook ever finish or does it freeze indefinitely?
It freezes indefinitely. Anyway when UFE is frozen, AutomationTool keeps working in background, only the GUI is frozen.
One last question, is the cook or packaging process completing?
If it’s just the UI that’s frozen, that is most likely explained by the fact that it is using a large amount of memory. I haven’t been able to reproduce the issue on my end, but if you are unable to complete your cook we can try to test this on a lower end machine to see if we can experience the same results.
I’m getting this problem when I cook or when I build, but more often when I cook.
On 4.12.5 I hadn’t these problems.
Unfortunately I haven’t been able to reproduce the freeze on my end which leads me to believe it may be an issue related to your particular hardware setup.
If you can provide a list of repro steps that I can take to consistently reproduce the freeze on my end, that would be great.
Also, take a look at the software conflicts wiki to make sure you aren’t using any other software that could be interfering. A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums
I’ve had this problem for a while. From 4.13.something, to 4.14.1, to 4.15. It’s some kind of conflict with the editor. It never happens when the editor isn’t running.
Hi . Perhaps you (or some colleagues) could try leaving the frontend up while you’re doing your work in the editor for the next few days. See if it ‘randomly’ happens like it does for us.
Hey Jin_VE,
As noted in my answer below, unfortunately we haven’t had any luck trying to reproduce this on our end. If you are able to determine a solid repro case for us to try, feel free to respond with a comment and I’ll be glad to take a look.
Thanks
After further testing (I left UFE running all day yesterday while working in the editor and also left it and the editor running overnight), I was unable to reproduce the issue, unfortunately.
It seems to have been a conflict involving the build tools. Just keeping it running while you work wasn’t enough. Also, it got fixed. I haven’t seen it since I moved to 4.16.2.
Fixed in 4.16.2 (as far as I can tell, and it happened to me many times per day before).
One note tho, I’m not sure the problem I was seeing was precisely the same as the OP. I don’t believe any of the build tools were running when it froze, it was itself using a bunch of CPU. I find if you cancel a build, often UBT keeps running for a while. You can kill the process and the other processes will die too.
