Thanks for help!
@Tangled-Universe: Memory should not be the problem, or ..... perhaps ....
The Render machine is a HP Intel 2Core (3 GHz) with 2 GB RAM. It was rendered in cropped sections. TG has got one CPU completely the other CPU was idle. It was rendered in cropped sections. First i cropped it in left/right. Then TG crashed after rendering the top and starting with the bottom (after nearly 4 hours!). Then I cropped ist in Top/bottom and started with the bottom. There TG chrashed after a few seconds. Ther must be something with the bottom.
If I reduce the render quality to 0.36 the render will run!
@old_blaggard: I disabled GI 'cause I use the Fill-light-clip from Oshyan. By now, TG is rendering the second and the third part (upper left and upper right with 0.85 quality. After that, i will post the .tgd
