Community Tutorial: Disable UbaSessionServer (UBA)

The Storage capacity can be adjusted.

/// <summary>
		/// The amount of gigabytes UBA is allowed to use to store workset and cached data. It is a good idea to have this >10gb
		/// </summary>
		[XmlConfigFile(Category = "UnrealBuildAccelerator")]
		[CommandLine("-UBAStoreCapacityGb")]
		public int StoreCapacityGb { get; set; } = 40;

So go to your BuildConfigurationXML and add this under the root:

<UnrealBuildAccelerator>
		<StoreCapacityGb>64</StoreCapacityGb>
	</UnrealBuildAccelerator>
