An Unreal process has crashed: UE4

Hello All,

I am using Unreal engine to create 3D environments for machine learning purposes. Following are the specs of my workstation

RAM: 64GB
GPU: NVIDIA GTX1080
CPU: Intel Core i7

Every now and then my 3d Environment crashes with the following message.

When I open up the crash log file, it says the following

[2019.01.08-06.53.33:562][434]LogD3D11RHI: Timed out while waiting for GPU to catch up. (0.5 s)
[2019.01.08-06.53.34:061][434]LogD3D11RHI: Timed out while waiting for GPU to catch up. (0.5 s)
[2019.01.08-06.53.34:562][434]LogD3D11RHI: Timed out while waiting for GPU to catch up. (0.5 s)
[2019.01.08-06.53.35:062][434]LogD3D11RHI: Timed out while waiting for GPU to catch up. (0.5 s)

This crash happens randomly. Sometimes it would occur with a few hours of my simulation start, other times it will run for about 9 hours and then give the same error.
For my application, I need it to run for at least 12 hours straight.

Is it the way I created my map in Unreal engine that may be exhausting up the resources? Can someone help me resolving the issue or point me in the right direction?

Thanks.
