What is a mch higher value?
I've tried it now max-nodes=2500000 but it still stopped after this message

My PC has 4Gb (but since it's 32 bits it cant use all 4gb).
Changing the graphics didnt help to make more memory free.
I guess I should make the area even smaller and run the splitter 4x instead of 2x.
Northern France incl Paris+Benelux+Germany is probably too big for this computer.
