Clustering job failed for system: error: 4 - 'Out of memory load

Hi All
I am working with Unity 2019.1.0f2 and I get the following error

Clustering job failed for system: 0xc5a1e23842d3478f4fe44ad20e39696f, error: 4 - ‘Out of memory loading input data.’.
Please close applications to free memory, optimize the scene, increase the size of the pagefile or use a system with more memory.
Total memory (physical and paged): 19010MB.

For it, Could anybody help me to fix it?
Thanks for your time
Alejandro

Well, that’s quite a bit of memory you are using there. What kind of project are you working on? At a glance, this does not seem VR related.
You might want to consider some kind of LOD, mipmapping, culling, or compression. But that really depends on what the heck takes up 19gb of memory…
