While 'Generate Lighting' GI cache filled to 194 GB and unity fires "failed reading" messages

Hello all,

I have a scene with many objects and when I start to bake the GI the cache fills up to 194GB and at step ‘3/11 Create System’ at the last job it produces many failed to read from…(see screenshot) messages.

(not ending)

I have cleaned the GI cache before starting to bake, it starts baking the ram fills completely up (32GB but no message in the console) after a while the ram usage is going smaller (below 10GB) and it works for a night.
But at the end of the around 4300 jobs in step3 it produces the messages and don´t continue.

my lighting settings:

(I have tried it with lower settings like indirect resolution at 12, lightmap resolution at 4 and lighmap size 128(?), without compress lighmaps and without ambient occlusion without success too)

In the last version 5.5 it takes long (2 days around, ram was sometimes nearly filled) but it works, but 5.6 ‘forces’ me to recompute the GI without success.
Its not a major problem because the scene runs without baked GI too, but I am interessted in if there is a chance to enlarge the GI cache greater than 200GB?
And the other question is, is it possible that 64GB of ram can solve the issue of the completely filled ram?

Has anybody some advice?

And sorry for my bad english.

Regards Dieter

Your indirect lighting resolution of 120 is way to high.
Usually i would would go from 4 to 20 with indirect lighting resolution but everything over that is probably not going to work.
