Araq, I have just seen your fix at github, thanks. nimble install nimsuggest
Now startup works fine again for large projects! BUT I am not convinced yet that USING it works fine again too. A fast test from within ned editor with "GOTO DEFINITION" or "ERROR CHECK" seems to eat still all of my 2 gigabyte. I will try to do these check from the command line tonight to ensure that the problem is really nimsuggest itself. And of course, its time to buy a box with more Ram,,,
