UEFN using unreasonable amount of RAM (60+GB)

General Issues and Bug Reporting

Summary

UEFN seems to be using an insane amount of memory when it doesnt have to and “commits” memory up to x4 of what its actually using. Could be due to verse script server as VSCODE was observed to have 25gb commited when UEFN was displaying this behaviour

Could be something with epicwebhelper?

Thank you, we’ll get this to the proper team to check into it.

I have this issue too. Even after installing 128GB of ram it would use it all and eventually crash. I avoid the issue now by running the Fortnite game/session on a seperate machine or mobile phone. This seems to stop the RAM usage going nuts. Curious if this solves the issue for you?
