4.8.1 memory leak

anonymous_user_0b9aa713 · July 13, 2015, 10:38pm

I appear to have a severe memory leak in 4.8.1, my memory usage seems to grow by about 1 Gigabyte per hour. Having the editor in the background seems to make this matter worse (Ie: Surfing the web/checking email with the editor running in the background).

Running Windows 8.1 with all updates.

Hi OEGInc,

We have an active investigation on a memory leak in the editor. It does not appear to be a universal problem and only happens for some of our users.

Would you mind sending in your dxdiag info and running a memreport for me?

When your memory gets out of control again, let it grow as high as you feel comfortable with. Then bring up the console with ~ and enter memreport -full. Rename the extentions on the .memreport file to .txt in the [ProjectName]/saved/Profiling/MemReports folder and then attach it here.

Here are the dumps… Right now it’s using between 4.5GB and 5.0GB of RAM… And it’s running very slow…

Are you running one of our sample projects or a custom project of your own?

I’m working on about 5 different projects at the moment and I honestly don’t remember exactly which project I was working on at the time, but I only glance at the sample projects and then I usually close them down - so I’m sure it was a custom project. It may have originated as a sample project though. I do remember that it was nothing special, all blueprints, no crazy stuff going on.

I’ve added your info to our ongoing bug investigating these memory leaks (UE-15297).

Hi,
To me the major issue about UE4 Editors is the memory, my pc has 16GB, when i open my project the editor shows “Mem: 1.038 mb”, 15 min later after a few changes (like copy/pastes) it reaches ~“12.000 mb” and starts frozzen. So i need to restart editor everytime it is near 12.000mb, it is so annoying. I think it is maybe because the number of objects you store in memory so the user can make “undos” e “redos”

Hi carf,

Out of curiosity, what project are you using? At startup, the Editor will only load what is needed for the startup level and no other assets. If you’re working in something like the Kite Demo or Elemental, you can expect the RAM usage to increase pretty quickly after opening the main level or opening up any of the larger assets.

12GB of usage is not entirely out of the ordinary with larger projects. Development takes significantly more resources than playing the packaged game that you end up creating.

Hi ,

Should i install more RAM on my PC ? 32 or 64 GB ?

Can you run a memreport (see here) when your memory gets to 12gb or close? Attach the .txt file it creates here.
