I’m building lightning in UE 4.23.0 on Ubuntu 16.04 and, following the logs, when static lightning needs to be built it gets timed out. Later, in the logs, an error LogInit: Error: Timed out waiting for the recipient (TimeWaitingSec = 60.015285) and afterwards an assert on Volumentric Lightmap:

LogCore: Error: appError called: Assertion failed: TaskDataArray.Num() == Exporter->VolumetricLightmapTaskGuids.Num() [File:/opt/UnrealEngine/Engine/Source/Editor/UnrealEd/Private/Lightmass/ImportVolumetricLightmap.cpp] [Line: 956]

Import Volumetric Lightmap failed: Expected 3047495776 tasks, only found 3073429500

Any clue on what is happening and how to fix it is very welcome. Mind that I have loopback address set up correctly as mentioned here and I had no problems doing it in UE version 4.22.3.
