Syncing to revision control uses a lot of RAM and then crashes

[xd_ItsKarMa]

Summary

When syncing to revision control, UEFN starts using more and more RAM until it can’t use more RAM and proceeds to give the error: “Out of video memory trying to allocate a rendering resource. Make sure your video card has the minimum required memory, try lowering the resolution and/or closing other applications that are running. Exiting…”

I have 12GB of video memory. 32GB of RAM.

Additional Notes

Local project already deleted, Unreal Editor files have been verified and reinstalled, PC has also been rebooted already. None of this seems to fix the issue.

It may be related to Virtual Memory, you have some moderate disk 0 usage, right around the time your mem, cpu & gpu max out.

Go to your advanced PC settings and change your Virtual Memory settings to min 64Gb or as much as you can get, but put the paging file on your least used disk, either 1 or 2.

Oh hang on 147 actors… it shouldn’t be doing that, check your custom stuff, there could be an issue with a material, run the Validate Project in the launch menu and see if it gives any warnings.
